When a naked man perches on a doorway waiting for somebody to enter. When they walk through the door, you jump down and slide your dick, balls, gooch, and asshole across the victims entire front.
“Did you hear that josh gave wyatt the mississippi snail trail??”
When you bust a nut on the floor and use your semen as lubricant to slide across the floor.
“Yeah man, I was trying to do the snail trail and I slipped and broke my fucking neck.”
