"GP" is an abbreviation often used by rollercoaster enthousiasts. It literally translates into "general public." It is often used to describe the majority of visitors to theme parks, as they do not typically know much about rollercoasters.

GP in general can make very dumb remarks regarding coasters, which in turn makes enthousiasts cringe.
1) "King Da Ka had a rollback earlier today. I could hear the GP screaming, because they don't know that they happen regularly."

2) "I just heard a member of the GP say that this rollercoaster travels through the air, without track for a few seconds."
