The ultimate form of revenge that a hammered dude can pull on his friends. All that needs to be done is saying, "That's it (pause) the dick's comin out." followed by the pulling out of his penis. A last resort type of revenge that cannot be topped, at least in the mind of the influenced.
(friend who has johns keys) Hey john did you lose your keys?
(John) ...don't you f**k with me. That's it... the dick's comin out.(pulls out penis)
