GP is a word used by roller-coaster enthusiasts, and simply means General Public (as in what non-enthusiasts would say/do).

The word is also used as a gatekeeping measure by some enthusiasts from letting their passions be flooded with non-enthusiasts.

NOTE: People in videos tend to say 'general public'.
1) Nemesis, at Alton Towers, is a ride not just popular with enthusiasts, but with the GP as well.

2) If you don't know what GP means, you're GP.

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..
