The act of tucking your dick and balls while bending over and simultaneously stretching the skin on your balls to portray a goat with batwing genitalia. This is a combination of the goat and batwing poses, therefore the victim of this sight gets 7 kicks plus the requisite "Fag!"
"Hey, I just gave Bill the goatwing. He's been crying ever since."
