When a man is fucking a midget, any style, and preforms a stunt on her that is shown in Jackass, whether that be a cum chug, an ass brand...etc.
Jim: "Hey, How'd it go with Charlene last night."
Bob: "It was great! we were doing doggy style, and since she's a midget I thought I would pull Wee Man's Revenge."
Jim: "Nice. What stunt did u do?"
Bob: "I branded a dick on her ass"
Jim: "Dude... weak."
