A warning sign — a behavior, trait, or pattern that indicates potential harm, toxicity, or incompatibility in a person or situation. Borrowed from sports officiating and safety signaling, red flags in social media slang primarily refer to dating but apply to friendships, workplaces, and more.
“He talked badly about every single one of his exes on the first date. Massive red flag.”
A phrase used to compliment someone who has perfectly executed what was expected or more. It implies the person grasped not just the literal task but the spirit, energy, and aesthetic of the moment — and delivered fully on it. Often used for fashion, performances, or any context requiring vibe accuracy.
“She showed up to the Met Gala in a fully custom look that matched the theme exactly — she understood the assignment.”
A romantic or emotional relationship that exists in an undefined gray zone — more than friends, less than officially partners. A situationship involves the intimacy and investment of a relationship without the formal commitment, labels, or clarity. Often characterized by avoidance of "the talk."
“We've been hanging out for six months but haven't defined anything — classic situationship.”
A positive signal or encouraging trait in a person or situation — the opposite of a red flag. Green flags indicate emotional maturity, trustworthiness, kindness, or compatibility. Spotting green flags early in a relationship is considered a healthy sign of self-awareness and dating literacy.
“He remembered a small thing I mentioned two weeks ago. Total green flag.”
A viral 2024 phrase used to describe behavior that is extremely modest, restrained, mindful, and presentable. Originating from TikTok creator Jools Lebron's videos advising people on how to present themselves professionally and politely, it became a widespread template for humorously praising or describing careful, considerate behavior.
“I wore a neat blazer to the interview, very demure, very mindful.”
A formative life experience that seems destined to happen and cannot be changed without altering who a person fundamentally becomes. Popularized by Spider-Man: Across the Spider-Verse (2023), it spread as a meme for inevitable painful or awkward experiences that "must" happen for character development.
“Getting rejected from your first-choice college is a canon event — it redirects you somewhere better.”
An expression of agreement, affirmation, or acknowledgment — similar to "okay," "understood," or "sounds good." Can also express that a challenge has been accepted. Originated in AAVE and spread widely through social media. The enthusiasm level is implied by context.
“"Meet me at 6?" — "Bet."”
A dramatic positive transformation — physical, emotional, professional, or social — usually over time. A glow up is visible and significant: the awkward teen who becomes a confident adult, the struggling artist who breaks through, or anyone who clearly leveled up from a prior, lesser version of themselves.
“Have you seen her lately? She glowed up so hard — different city, new career, completely radiant.”
Natural charisma, charm, or the ability to attract others effortlessly — especially in a romantic context. Someone with rizz seems to captivate people without trying. Can also be used as a verb: to rizz someone up means to charm or seduce them.
“He walked into the party with unspoken rizz — no pickup lines, just vibes.”
A distinct phase or period of someone's life, aesthetic, or personality — particularly one currently being embraced with full commitment. Popularized by Taylor Swift's "Eras Tour," being "in your [X] era" means fully leaning into a particular identity, vibe, or lifestyle without apology.
“I'm in my unbothered era — no drama, just growth and good vibes.”
A personal phase characterized by emotional detachment from drama, criticism, and things that previously caused anxiety. Being in your "era of unbothered" means you've consciously decided to stop letting trivial stress, haters, or social pressure occupy your mental bandwidth.
“I deleted social media and I'm fully in my era of unbothered — haven't checked my mentions in weeks.”
A playful abbreviation of "delusional," used to describe someone (often oneself) who holds unrealistically optimistic beliefs or interpretations, particularly in romance or career goals. "Delulu is the solulu" (delusion is the solution) became a popular subversion, reclaiming the label as a form of manifesting confidence.
“I'm fully delulu — I'm applying to every dream job with zero qualifications.”
Subtly introducing a new romantic partner on social media without explicitly announcing the relationship — posting a photo that includes them without tagging or explaining who they are. Borrowed from startup terminology where a product is quietly made available before an official announcement, allowing for low-stakes feedback.
“She soft launched him with a blurry photo of their hands. Comment section went crazy.”
The mental state resulting from excessive consumption of low-quality, repetitive, or extremely niche internet content — particularly short-form video. Someone with brainrot has been so thoroughly marinated in online memes and references that their humor, speech, and thinking reflect it constantly. Can be self-deprecating or affectionate.
“My brainrot is so severe that I referenced a Minecraft YouTube meme in my thesis conclusion.”
Non-Playable Character — a term borrowed from video games to describe a person who seems to act on autopilot, lack individual thought, follow social scripts unthinkingly, or show no original personality. An NPC mindlessly agrees with mainstream opinion without independent reasoning.
“He just repeated the talking points without any nuance — total NPC behavior.”
Caught undeniably and in high-definition clarity — having your misdeed, hypocrisy, or questionable behavior documented on video or screenshot with no room for denial. A reference to 4K ultra-high-definition video, implying the evidence is crystal clear and irrefutable.
“He said he was at home sick but was caught in 4K at the concert.”
Short for "suspicious" — describing behavior, a person, or a situation that seems sketchy, untrustworthy, or questionable. Popularized globally by the game Among Us (2020), where players accuse each other of being the impostor. Now used broadly for anything that doesn't seem right.
“Why is he being so quiet? That's pretty sus.”
The behavior or belief that one's own life is a story where they are the protagonist and everyone else is a supporting character. "Main character energy" can be positive (living boldly and authentically) or ironic/negative (being oblivious to others' needs because you're too focused on your own narrative arc).
“She walked into the office wearing a cape — pure main character energy.”
Affects you more deeply, or in a different way, than expected or than it normally would. Something that "hits different" has an unusual emotional resonance due to circumstances, timing, or personal context — the same song at night, the same food when you're homesick, or the same joke after a tough week.
“This song hits different when you're going through a breakup.”
Publicly and explicitly announcing a new romantic relationship on social media — posting a clear, tagged photo and leaving no ambiguity about who the person is. The bold, all-in counterpart to a soft launch. A hard launch is a confident statement that you're officially "official."
“After weeks of mystery, she hard launched him with a full caption and tag. The internet lost it.”
