"KO" is the equivalent to the meaning & abbreviation of the letters meaning "OK" and was used on "Mork & Mindy", which is a t.v. series that had aired from 1978 to 1982. Mork is one of the main characters in the series, and an alien from the planet Ork. He would commonly reverse the proper order of human words and phrases that he spoke, by mistake
"Owie! Shazbot, shazbot, SHAZBOT! I stubbed my little toe when I tripped over the footstool Mindy, and it hurt!!! You didn't even ask me if I was KO!!!"

(Mindy replies)
"Oh, Mork! I'm sorry- did it hurt? I think you meant to say that I didn't ask you if you were "OK", on Earth we ask if you are OK if you hurt yourself, not "KO"!!!

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.”
