Justine Kish
Kish will always be the UFC fighter who pooped her pants in the ring. It’s unfortunate but that’s her athletic legacy in a nutshell because nobody remembers anything else about her. She fought Felice Herrig in a UFC event when her body betrayed her in the most unfortunate way (via Men’s Health).
Herrig had Kish in a compromising position and was choking the life out of her. This triggered the Valsalva maneuver that causes the diaphragm to work. It also places stress on the lower parts of the body as Kish discovered. In the end, she left a mess that no one wanted to see.
