Louf n One who suffers a momentary lapse in clear thinking. Originally Loof, coined by 7-year old JFH to describe his sister after hearing that scripture prohibits calling another a "fool". Louf is a lighthearted though derogatory term of less severity than fool, idiot, turkey or dolt.
"You louf." said to one who has just done or said something silly.
