"Have you given her the old hot cosby yet?"
"No, we saw a movie and now we're going to the park"
"Butters, we don't have time for that, I told you, you need to cut to the chase with the hot 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
