Usage example: Did you see Ostertag go after that referee last night? That was an act of Artestean craziness.

Word History: As far as we know, this word is an original creation of the Basketbawful Staff. It came into use shortly after the infamous
riot-that-shall-not-be-named. It is used to describe any action or behavior that is equal parts ridiculous, unpredictable, and insane.
