An insult worse than the likes of "your mom". Often used by those with a higher intelligence or beauty than the victem of the verbal assult. Derived from fat (an over eating side effect)and medusa (that bitch in greek mythology).
"Why you bein' such a bitch Kimberly?"
"Shut yo face you Fat Medusa!"
"Oooooooooo..."
