Cock wiggle

When a nude male shakes his hips to make his erect penis swing back and forth and slap against his body; often performed by male strippers to provoke women's squeals during bachelorette parties.

Girl # 1: "That cock wiggle he does is impressive!"
Girl # 2: "Shit, he can slap that cock in my face anytime!"
Girl # 3: "Wooohoooooo!!!"
