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.
"That meal we had was catsex."

"You're an idiot."
"Catsex!"
