As a transitive verb: "Hey, Scotty! I heard ya gave ya woman dry wrong-un!"
As a noun: "Hey, I heard you got some on the week-end, Scotty. Do you do her up the wrong-un? Ha, ha, ha, ha, ha!"

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.

“Ever since the glippy hit, food feels optional.”
