Sleep on 

To sleep on someone means you don’t believe they’ll actually achieve something they said they would or will do. It’s basically someone calling you bluff on something you say you’ll do, but instead of them verbally calling you bluff, they’re thinking it. Its thinking that someone will stay stagnant in a journey, process, career, etc. It’s a lack of respect towards that person either because they haven’t done it before or because you don’t believe in them. Basically, if someone is sleeping on you, you’re not a threat nor respected by that person and this is a time to prove that person wrong.
The other day, I told someone I wanted to be an oscar nominated actress. She laughed in my face and said “yeah alright sure thatll happen”. I laughed and told her “don’t sleep on me”.

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.”
“That summer body? Yeah, glippy assisted.”
