A sexual deviant that often has sex with a freak that doesn't care where he sticks his dick as long as it is a hole (the stuchle). The stucle fucker, stuchle, and a third freak (often a 400 lb women or a tranny) will have three somes while the stuchle fucker is passed out or drunk.
stuchle: You want to take shots of Jim Beam and have sex with the coke dealing she-male downstairs?
guy: What do you think I am? A stuchle fucker?
