Mud Cup

A disposable plastic drink cup with some water in it used by cigarette smokers as a makeshift ashtray. After a while; it becomes filled with so many used cigarette butts, the contents of it look like muddy tobacco sludge.

At Mike's party; I reached over for my beer cup. Since I was drunk, I didn't realize I was about to take a swig from the Mud Cup. Thank God someone stopped me before I chugged the whole damn thing.

Peruvian Mud Cup

When the female partner empties a gallon of milk inside her asshole, the male partner then lays directly below the woman's anus and opens his mouth as wide as possible to receive a huge load of poop/milk diarrhea into the his mouth, having the appearance of chocolate milk or mud.

friend 1: Daniel you finished all the milk!?!?

friend 2: Yeah man last night my chola gave a full serving of a Peruvian mud cup:)

friend 1: Nice!!
