Guillotine 

While doing a standing 69, with the girl being suspended and upside-down, perform a tombstone piledriver on her while your dick is in her mouth. If performed correctly, when her head hits the ground, her jaw will slam shut and your dick will be bitten off, leaving you with a raw, bloody stump and a serious drop in your testosterone levels. For masochists and noobs only

Jeff: Will, you voice is all high and you look like you've been kicked in the dick.

Will: I don't have a dick, i guillotined myself.
