A prank move pulled by two conspirators in a men's restroom that does not have barriers between the urinals. Ignoring proper urinal etiquette, the two prankers come up on either side of a lone pisser and angle 45 degrees so as to piss into the same urinal as the man being pranked. Usually complemented with a conversation across the middle man.
