A threat. The act: getting a hot girl/prostitute/total slut bag to go in and start rubbing/sucking/engaging in sexual
congress with the subject of your threat. Then, shortly before ejaculation, but at full and inescapable arousal, you burst into the room and punch
said target in the head
of the dick aiming towards
the base of said penis. The result: complete
and utter destruction of said person via ruination into the base of their wang.
Jims: Dude, don't go there. I'll give you a lead zeppelin.
Slapdick: The metal band?
Jims: No the ruination of your dick
