When you are fucking a chick from behind either anally or vaginally, you proceed to donkey punch her; while she is stunned you take a shit on her head while saying "Your turban is dirty!"
Frank: you know that chick i took home last night?
Eddie: oh yeah, she was pretty hot, you bang her?
Frank: goddamn right, gave her the dirty turban too!
Eddie: oh thats fucking SICK!
