Glossary: Asshole Sprain

An affliction that besets boxers and other people who do a lot of punching. If a punch lands on the knuckles of the little and ring fingers, there is a chance of spraining the ligaments or pulling the muscles that hold the metacarpal bones out of place. You'll know you have it because there's a pain shooting right down the back of your hand, right between the knuckles of where you hit improperly.

An asshole sprain is different than a boxer's fracture or boxer's knuckle, which are related, but different maladies.

Called an asshole sprain because you get it from punching like an asshole.

Mom: How's boxing going? You hurt yourself again?

Me: No, I'm doing pretty good. My elbow feels better, but I did get an asshole sprain though.

Mom: Jiu-Jitsu really is gay, huh Mikey?

Me: ...
