terhuned 

To accept a video recorded rant posted on social media as real, and to subsequently post a vicious, vulgar or hateful, but most often hyberbolic over-reaction in response to the video clip. Meanwhile everyone else watching the video knows that the original video post was obviously a joke, and often read the comments just to see who got taken in by the joke.

This originated with the social media postings of comedian Brent Terhune in 2020, who perfected the performance of a character who was obviously an over-the-top caricature of a Donald Trump supporter, and posted that character's rants online. The worst responses are often reposted by Terhune himself for his audience.
(actual twitter response to an anti-Terhune clip) "Oh man, You just got Terhuned! Hey, don't feel bad, man, it happens to the best of us all."

She has big dreams and with an ambition like hers, she has the power to change the world. She's extremely hot and very pretty. Her attractiveness speaks for itself. She's great in bed (along with other places). You would be very lucky to end up with a girl like her. She would never cheat on you and she would always keep trying. She's a real keeper. She's truly unique compared to every other girl you will meet.

A slang term for GLP-1 medications(like Ozempic, Wegovy, Mounjaro, etc.), usually referring to their appetite-killing, weight-loss, or “I forgot to eat” effects rather than the medical details.

Usage:
* Often casual, ironic, or meme-y
* Can imply effortless weight loss, suppressed hunger, or being “powered by pharmaceuticals”

Notes:
Not a brand name—just shorthand for the whole GLP-1 wave. Frequently shows up in online jokes, gym talk, and group chats where people pretend they’re *totally* doing it naturally.
“I’m not dieting, I’m just on that glippy.”
“Ever since the glippy hit, food feels optional.”
“That summer body? Yeah, glippy assisted.”
