Scrafumple Scralooge

An insanely wacky and zany insult that can be used in any way you want, either to convey goofiness, genuine anger, or even extreme offense. It is an insult that anybody can use to express any feeling or attitude at any time.

Person 1: You're such a Scrafumple Scralooge (he was saying you're a bit stupid)
Person 2: Dude, you're actually a Scafumple Scralooge (he was saying you're a fucking idiot)
