Koster Foster 

A Koster Foster is a/are sad cunt(s) who can only get by and survive in life by the means granted to them by a host, directly implying they are parasitic. Persons who use lies, deceit, manipulation, abuse, psychological discourse and societal/social sympathies to acquire a foundation to provide for themselves the necessities and luxuries of life whilst giving nothing but lackluster entertainment of flesh in exchange for everything else. Coveted by pathetic beta boys who would never/only very luckily catch the eye of and entertain the opposite sex by subscribing to a norm of paying for bad pussy. Revered by even sadder and often more pathetic females who only value their lives in terms of the price tag attached to their involvement.
You see that girl over there that has no job, car, lives at home with her mom and spends all her time slinking around the same bar every night? She is looking for prey, she is such a Koster Foster its not even funny.

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.”
