instanity

The deranged, unhinged state of mind caused by obsessively stanning someone or something. Symptoms include irrational behaviour, public meltdowns over fan drama, and an inability to distinguish reality from fanon.

Basically: when stanning becomes insanity.

“She wasn’t just a Swiftie. She had full-blown instanity.”

“Their whole Discord server is descending into instanity over that leaked rehearsal clip.”

“This level of instanity should be classified as a psychological condition.”

Install CS:S

Word used in the Garry's Mod community (sandbox game). Some custom maps made from players require players to install the game Counter-Strike : Source in order to have the materials and props included in the map. This is because Garry's Mod has a feature that allows you to spawn assets from (some of the) other games that also use the source engine (the same engine Garry's mod uses), so some players create maps that use these assets for players who also has the game required for the map. But this word is now not used since the July 2025 update that made the game include contents from Counter-Strike : Source and Half-Life 2 episodes by default.

Instagram Reel Scholar

Someone who thinks a 12-second Instagram Reel is the same as a PhD. Gives unsolicited life advice based entirely on vibe-based pseudoscience and captions like “READ THAT AGAIN.” Least qualified person in the room, most confident voice in the group chat.

“He watched two Reels from a shirtless guy in a garage and now, as a full-fledged Instagram Reel Scholar, he’s lecturing me about ‘ancestral masculinity.’”
