fatch

A term used to describe someone who thinks they're clever but ultimately lacks the capacity for intellectual thought... and everyone fucking knows it. Used when someone has proven their stupidity without a doubt.

"That fatch took a physiology class and now thinks I wanna fuck my mom."
"Everyone at my family reunion thinks climate change is a myth, what a bunch of fatches."
"Kevin does not believe in evolution. Kevin is a fatch... fuck Kevin."
