if I find an image or gif or something I will, but a description will have to do for now.
Sid Vicious (wrestler guy, not Sex Pistols guy) is in a match in WCW. He's on the top rope, jumps off and kicks a guy in the head. However, he lands in such a way that the leg he's landing on bends at a really sick looking angle at the shin, so that from part of his shin down is like perpindicular to the rest of his leg.
