When a men's restroom
Consists mostly of urinals, or when the men in said restroom are mostly pissing. One such example would be at a sporting event where men are in line to use the urinal.
John: "I went into the restroom and there was piss all over the seats, and everyone was waiting in line!"
Mike: "Sounds more like a pissitorium to me."
