bandsaw

A high difficulty sexual maneuver. One who attempts the bandsaw requires: one pair of golf cleats, one pair of thumbs, one willing victim.

First, place your cleated foot upon the back of said victim's head, applying enough pressure so they can squirm but not escape. Next, hock the largest wad of spit you can muster onto their butthole, and fasten first thumb deeply into the slippery crevasse. Once first thumb is secured properly, fire second thumb into one's own butthole. With a firm grip upon each sphincter, pierce the victims funzone with your love rocket.

Dude, it's not a bandsaw if you put both thumbs in your butt
