Chicxulub

The word Chicxulub was an insult in the Mesozoic Era. The asteroid that killed was called Chicxulub. Because the dinosaurs could not use the word shit (the word shit was only invented a few thousand years ago, where the dinosaurs lived a few hundred million years ago), the dinosaurs had to use the world Chixulub. Scientists argue wether this word was truly the first insult in history of earth, but they are not sure either.

Dinosaur 1: What is that glowing thing up there?
Dinosaur 2: What? Where?
Dinosaur 1: There! (points up)
Dinosaur 2: Oh Chicxulub!

Chicxulub asteroid

Something that solves many problems with a single action, i. e. killing many birds with one stone. Named for what was responsible for the extinction of dinosaurs; since birds are dinosaurs, that means that the asteroid (a stone) killed many birds.
