Fahrenheit 451 

Fahrenheit 451 is a novel by Ray Bradbury, depicting a world in which books are outlawed, and firemen start fires, not put them out. The main character is Guy Montag, a fireman.

The title is quite clever, because at 451 degrees Fahrenheit, paper combusts.

The son-of-a-bitch Michael Moore used the title's theme in his movie "Fahrenheit 9/11", to Ray Bradbury's disapproval.
I read Fahrenheit 451 yesterday, and realized that books and the ability to spread wisdom are very valuable.

This Caucasian lady comes by and sits next to him... she went KARENHEIGHT 451* called the police... luckily they arrested her ass for wasting their time and being belligerent... she’ll probably get fired too.”

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.
