Ding Biscut 

Someone who is just barely able to function in society. This person usually forgets things, leaves things behind, loses things, often misplaces his/her children, runs into stationary objects, forgets where the car is parked, can't follow directions worth a shit, finds books without pictures to be too much work, uses the words "um", "totally" and "like" to excess, cries to get out of trouble and has that rare talent of being able to burn water.

Guy #1" Jesus Christ she is a ding biscut!

Guy #2: I know but she sucks a mean cock and she is smokin' hot so I can't get rid of her.
