When your fucking a girl in the ass while at your kitchen table and eating delicious beef wellington.
Last night my girlfriend made me delicious beef wellington so i figured i would take advantage of the situation and performed the dirty cosby.

It is when after having a roofie slipped to you, the person performing the cosby shoves rocks into your vagina and then pisses on you. after then, he shits his pants, grabbing a hand full of shit and smearing feces onto your face
