on the same wavelength 

Being on the same wavelength is similar to the expression "We're totally on the same page" or "Great minds think alike" It means that you and the other person are similar in thinking at that very precise moment. Often this happens when you voice a thought and someone else says the exact same thing or something similar. It just means you had the same opinion on something about a certain topic, issue or whatever.
"That skirt is to die for. It would go so well with the heels I bought last Saturday"

"Was just thinking the exact same thing!"

"Haha, we're on the same wavelength I guess!"

fache-couture 

French slang, which translated, means "bull's fashion" but basically equates to "hyper trendy" or overly trendy. Used when a person wishes to express distaste at the latest fashion trend/fad, because it seems that everyone has a certain item of clothing or is wearing it. This term is most frequently heard in Paris but is slowly spreading to other parts of France.

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.”
