D.U.F.F
Literally stands for Designated Ugly Fat Friend. This is the bitch who comes out of no where to cockblock you when you are about to get a chick home with you. She is often recognizable by her fat ass, bad hair and sour disposition. Her main goal of the night is to fend off any advances on her friend so she will have company at the diner when she is stuffing her fat face with an omelet and a side of disco fries while she bitches about anyone and everyone. The D.U.F.F can be defeated with a high level wingman, but you will be expected to return the favor; a job not for the faint of heart. A naked D.U.F.F often smells like a box of crayons.
"Dude, I was about to bag this chick, but then her army of D.U.F.F's came out of no where and pulled her away. She must be a Volleyball player!"
"Did you Fuck the chick at the party?"
"No Fuckhead, I got Duffed!"

Glippy
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.
