Member of an extremist republican club of the French Revolution founded in Versailles 1789. Helped by Danton’s speeches, they proclaimed the French republic, had the king executed, and overthrew the moderate Girondins 1792–93. Through the Committee of Public Safety, they began the Reign of Terror, led by Robespierre. After his execution in 1794, the club was abandoned and the name ‘Jacobin’ passed into general use for any left-wing extremist.

Jacobins 

The Jacobin Club was the most famous political club of the French Revolution. So called from the Dominican convent, where they originally met, in the Rue St. Jacques, Paris. At that time, the term was popularly applied to all supporters of revolutionary opinions. In contemporary France it refers to the concept of a centralized Republic, with power concentrated in the national government, at the expense of local or regional governments.
The Jacobins sure were a rowdy bunch, always wanting to have a revolution and FUCK WOMEN.

jakobina 

Jakobina is the most beautiful and intelligent person I know. She is a asshole, but in a funny way. You can talk with her about everything. She cares for you, but she can't really show it. Sometimes it seems like she doesn't care at all but she does. She will always listen to you, even of you call her at 3am. She will call you at 3am because she needs someone to talk about her OTP. She will laugh at you when you fall down. She will help you with your homework and tries to explain math for you. She doesn't say that she likes you, she doesn't need to, you can see it from her actions. She seems cold but if you talk with her about something she really loves, you can see her eyes sparkle. She has the cutest smile when she sees her OTP. She's the most amazing person you can know.
A: "She's like Jakobina"
Funny, sadistic, intelligent

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.
