middlepisser 

That guy who uses the urinal in the middle in a public toilet forcing the next person to use a urinal directly adjacent to the one he is already using thus contravening the understood rules of urinal etiquette that require one to go to the furthest urinal to allow for an empty urinal buffer zone between oneself & the next patron. (similar to heterosexual buffer seat at movie theaters)

Every time I've gone into the bathroom tonight some middlepisser is taking up the urinals, so I just went into a stall.
