Irish drive-by
Urinating in a public, men's bathroom that has more than one urinal and opting to, rather than use one urinal and stick to it, run the gauntlet and piss in all of the urinals in a continuous stream. Usually performed while drunk, although sober attempts are acceptable.
I got out of the movie and there was nobody there, except this old dude taking a shit. So, I did an Irish drive-by.
