What is a GIB

Is it a Giant Inverted Boomerang? Because I've been hearing about this with Deja Vu and its problems.

Deja Vu is a GIB, which is the factory name for a Deja Vu. Giant Inverted Boomerang=GIB=Giant Inverted Boomerang. Six Flags calls a GIB a Super Invertigo instead of a GIB.
Is that confusing enough? I tried to make it as confusing as your question.

Well I'd think Giant Inverted Boomerang is kinda self-explanatory.
