Radiclysmic

Radiclysmic is the theory that anyone or anything reaching "Absolute Radness" would inevitably cause the destruction of the universe through an intricate chain of subspace explosions, due to the overproduction of Rad particles in nearby stars and star clusters. Not unlike division by zero.

If "Absolute Radness" is achieved in deep space with no nearby stars however, it is hypothesized that there would be little to no repercussions. It is also hypothesized that nearby personnel would become "Totally Rad", phasing them out of what is known as "Weak Space", and into another dimension populated by all the raddest things and raddest people.

It's also an adjective to describe something really freaking awesome.
Ex. 1

Kyle: I got all the achievements in Battletoads.

Kyle is phased into Rad Space, destruction of the universe is imminent.

Ex. 2

Kyle: I got all the achievements in Battletoads.

Jeff: Radiclysmic.

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.”
