An elaboration on the sexual maneuvre of Donkey Punch involving another girl who is having oral sex performed on her by the victim of the donkey punch. The donkey punch should be forcefull enough to get a vaguely amusing reaction out of the "munched" (oral receiving) partner.
To add to the donkey aspect, stick a carrot in somewhere. Why not, you twisted people.
Upset girl: That bastard punched her in the back of the head while she was going down on me!
Compassionate friend: Hah! You got donkey munched!
