A nonsensical word that can be used as either a verb, adjective, noun or almost anything else. Usually accompanied by various pictures of cats copulating. If anyone knows more about the origin of this odd word, I encourage them to write a better definition.

Get the catsex mug.
Almost a phrase like "supercalifragilisticexpelidocous." mainly, its a way to say any noun, verb, etc. its mainly all dependant on tone, and almost meant to be responded to with "wait, what?" (However, Catsex would normally be a synonym for like, cool, or sweet, or superspecialawesome)
"Im sorry i didnt finish my homework, i was too busy with catsex."
