Born 1981-1996

You Only Live Once. The justification for any impulsive, reckless, or self-indulgent decision. "I ordered the dessert. YOLO." Peak usage 2011 to 2013, substantially accelerated by Drake's 2011 song "The Motto." Used sincerely then ironically then as self-aware pastiche. Now primarily ironic. The philosophical idea it expresses is ancient; the abbreviation is not.

The anxiety that something interesting is happening somewhere else, and you are not there. Social media amplified FOMO by making the activities of others visible at all times. Coined by Patrick McGinnis in a 2004 Harvard Business School newsletter. Entered mainstream usage around 2013. Now a recognised psychological phenomenon studied in relation to social media use and anxiety. Its counterpart, JOMO (Joy of Missing Out), is the contentment of staying home.

Performing the tasks and responsibilities associated with adult life, as if they require special effort and deserve acknowledgement. "I cooked a proper meal today. Adulting." The word treats adulthood as an achievement rather than a condition, reflecting both genuine difficulty (many millennials entered adulthood in the 2008 financial crisis) and a self-deprecating awareness of their own reluctance. Broadly mocked by older generations. Broadly recognised by the people using it.

Mainstream, unoriginal, following trends without apparent individual taste. The basic girl or basic bitch was a cultural archetype: pumpkin spice lattes, Ugg boots, leggings, and a complete alignment with whatever was popular. "Basic" implies a lack of distinctiveness, an unexamined consumption of whatever culture offers. Used mostly about women and mostly by women. The term was criticised for shaming ordinary enjoyment. Its defenders argued it targeted conformity, not enjoyment.

Perfect, impeccably done, exactly right. Particularly applied to eyebrows: "eyebrows on fleek" meant perfectly shaped and filled. Originated in a six-second Vine video in 2014 by a user called Peaches Monroe. Spread globally within weeks. Was already considered dated by 2016. An example of how internet culture can take a phrase from a single video to total ubiquity and back to cringe in under two years.

A term of endearment for a romantic partner or someone you admire. "Bae" is widely claimed to be an acronym for "before anyone else," but it is more likely a shortened form of "babe." Either way, it was ubiquitous in millennial vocabulary from around 2013. "Bae caught me sleeping." "She is bae." Now dated to the point where using it unironically dates you precisely.

A group of friends whose relationship, appearance, or activities represent an aspirational ideal. Seeing a tight, glamorous, or apparently close friend group and thinking: I want that. "Squad goals" was an expression of envy dressed as admiration. The phrase peaked around 2015 when Taylor Swift's friend group was its primary cultural reference point. Now used almost exclusively with irony.

Expressing contempt or disrespect for someone in a subtle, indirect way. Not an outright insult: shade is delivered obliquely, through a tone, a look, a seemingly innocuous comment that everyone present understands as a put-down. From ballroom and drag culture, codified in the 1990 documentary Paris is Burning: "I don't tell you you're ugly, but I don't have to tell you because you know you're ugly." Shade requires wit. An obvious insult is not shade.

A complaint or self-deprecating remark that is actually a boast in disguise. "I'm so exhausted from all the travelling for work." "My arms ache from carrying all my shopping from the farmers' market." The speaker is drawing attention to something enviable while pretending to find it burdensome. Coined by writer Harris Wittels around 2010. The word for the behaviour made the behaviour visible in a new way, which may have made it slightly less common.

A sharp, swift, and decisive response to criticism or an insult. A clapback does not defend: it attacks. It turns the criticism back on the person who delivered it. From AAVE and hip-hop culture. Celebrities clapback at tabloids. Public figures clapback at critics. A good clapback requires precision and confidence: too slow or too mild and it isn't a clapback, just a late reply.

Evidence. Screenshots, records, proof that something was said or done. "Show the receipts" means produce the evidence. In an era when everything is documented, receipts are always theoretically available. Being caught without receipts when you claimed something, or having receipts produced against you, is a significant moment in online disputes. The metaphor is from paper receipts: proof of transaction.

A suggestion to "watch Netflix together" that is understood by all parties to be an invitation for something other than watching Netflix. The phrase became a meme around 2015. It works because it is a polite fiction: both parties know what the invitation means, and accepting it constitutes an agreement. The phrase is now so widely understood that it no longer serves its original function as plausible cover. Netflix has acknowledged it. The cultural moment has passed.

An expression of being so overwhelmed, amused, or emotionally affected that you cannot complete the sentence. The inability to finish is the point: the feeling exceeds language. "I can't even" became a shorthand for extreme emotional response, positive or negative. Mocked extensively, used sincerely, eventually became a self-aware cliche. The ellipsis at the end is part of the grammar.

Used as an intensifier, often in situations where nothing literal is happening. "I literally died." "I am literally the worst." Millennials' use of "literally" to mean "figuratively but emphatically" attracted more complaints from language prescriptivists than almost any other slang development of the era. The usage is not new: the Oxford English Dictionary notes its figurative use dating back centuries. The volume of millennial use is what made it visible.

Something aspired to; an ideal to aim for. Applied to relationships, bodies, friendships, careers, and interiors. "Relationship goals." "Life goals." "This kitchen is goals." The word colonised Instagram captions around 2013 and was attached to everything enviable. It functions as a compressed expression of aspiration: I want that. Not necessarily a plan to get it. Just the acknowledgement that it looks good from here.

Excessive, over the top, doing too much. Dramatic beyond what the situation calls for. "She's so extra." An eight-course dinner for a Tuesday night is extra. Arriving at a casual party in formal wear is extra. Can be a criticism or said with affection, depending on tone. From AAVE. The implication is that the person is performing for an audience that didn't ask for a performance.

Extremely enthusiastic about something, used as a positive. "I'm obsessed with this restaurant." Not a clinical term in this usage: obsessed simply means you think about it a lot and feel strongly positive. Millennial enthusiasm often reached for clinical or extreme language to express ordinary feeling. "Obsessed," "dying," "deceased," "I'm screaming": all expressions of delight that escalated the language of appreciation beyond its literal content.

Intentional activity to maintain or restore physical, mental, or emotional wellbeing. In clinical contexts: essential practices for managing chronic illness or mental health conditions. In millennial popular culture: a bath, a face mask, a night in. The term moved from medical literature to Instagram in one of the era's more interesting linguistic journeys. Both uses are legitimate. The commercial appropriation of self-care to sell beauty products is the less legitimate development.

Work, but more emphatic. An exclamation of encouragement when someone is performing, dressing, or presenting exceptionally well. "Werk!" is shouted approval: you are doing it, keep going. From drag and ball culture via RuPaul's Drag Race, which brought large amounts of drag vocabulary into millennial mainstream usage. The deliberate misspelling signals its origin: this is not office work, it is performance.

Laugh out loud. Originally a genuine expression of amusement in early internet and text culture. Migrated into a punctuation-like function: a social softener used to signal that a message is not meant seriously, or to indicate mild amusement rather than actual laughter. "I'm going to be late lol" does not indicate laughter. It indicates mild embarrassment and a desire to soften the news. Millennials were the first generation to use LOL in spoken conversation, which alarmed their parents.

Totally, adorable, and amazing respectively, compressed and affixed with diminutive endings. Part of a broader millennial tendency to truncate and soften words: "whatevs," "obvi," "cray," "defs." The effect is warmth through informality. The words are slightly childlike by design. They signal closeness and ease rather than precision. All three are now dated to a degree that wearing them unironically marks you more precisely than a birth certificate.

A preamble to a statement that is either genuinely candid or slightly softened by the admission that honesty is about to follow. "TBH I don't like that film." Also used in teen social media culture around 2012 as a post soliciting personal feedback: "like this for a TBH" meant like this post and I'll tell you what I honestly think of you. The results were sometimes kind and sometimes not.
