A person who can not control the direction of their piss.
When a grown man is sitting in a car and instead of getting out to pee in a bush, gets a 20 oz coke bottle and decides to piss in it, the end result is piss in the air vents, on a skateboard, in a cupholder, and on cell phone all because of their silly string.
