The process of doing two 180 degree rotations while sliding on a rail on skis and then landing with your testicles on the rail. Pain may be involved in such a trick, especially for the gentlemen.
Billy: So what trick are you going to do in the snowpark today.
Johnson: I Dunno, maybe a double switch-up on a flat rail.
Billy: Oh golly Miss Molly, i think you should go for a triple switch-up.
Johnson: Are you crazy?! If I were to attempt such a trick and land on my goods on the 3rd switch-up, I could pull off a Wankenstein.
Billy: Good point. What was I thinking?
Johnson: You weren't thinking Billy, and that's what makes America how it is today.
