Similar to a showergirl. Basically, it's a male recipient of the famed and disgusting golden shower.

one who likes to get his groove on in and out of the shower. A showerboy will groove it out under any circumstance!
Its just like when you have to go to Danny's in Windsor, and you are so flustered with all the action going on, and then a showerboy turns the heat up even more, with a thrustful pelvic giration.
