Word of the Day on October 17, 2026
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.”
