Laughing Silently Internally . This acronym is meant to take the place of LOL which stands for Laughing Out Loud. It is my belief, and I think I can speak for millions of others, that the acronym LOL is overused and not meaningful. People have overused it as a quick and easy way to say that they find something funny. They are probably not really laughing out loud. LSI is a way to quickly say that you find something funny but being truthful. Now when you say LOL it will have even more meaning.
example: a facebook post
This video is so funny. LSI.

example a response to text message
You are retarded! LSI

As an adjective:
I was checking out this blog and it was funny. Had me LSIing

now you can use LOL when more appropriate:
When you told me you were destined for greatness you had me LOL. I was drinking a cola at the time and shot right out of my nose!

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.
1. That Burberry scarf is so fache-couture.
2. That purple American Apparel hoodie is so fache-couture.

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.”
