A running reverse backflip that can be done off a springboard or a platform. Many people can't do them due to the mental block of going upside down, but they really aren't that hard.

Gainer is slang for the diving trick reverse. The category number is 300. For Example, a reverse flip (usually the term for gainer) is 302, and reverse double would be 304. A reverve is done when walking forward with a full approach, and not running. Many inexperienced divers run on the board, and could very easily slip. Gainer 2 and a half, 305, pike is the dive Greg Lougains hit his head on in the Olympics.
My personal favorite dive is a 304 tuck, which is a reverse double, but I like to call it, "gainer double."
