Some years ago when I was in the frat there were some guys who would do this, especially before going on a road trip. Before that I never would have thought, to much risk of getting shower water in the beverage, after I heard them talk about it I always associated it with some dudes I didn't care for grabbing folding chairs and having some hair of the dog to keep the hangover at bay while in the car. Oh, and there weren't individual shower stalls or anything like in the dorms, more like an old gym shower room. It was a social event for them.
No desire to try it.
