An acronym standing for Group
Poop. Much like women and their periods, when men begin living together, their
poop cycles coordinate. A group
poop is when these strapping young whipper-snappers, members of a team, or other cohesive unit, as it were, congregate to
poop together in the same facilities. While defecating, they listen to the collective bowel calisthenics and engage in witty banter or bathroom games (i.e. kicking open the stall door/paper towel bombings). Also see P.I.A.G..
