Aikido

"Aikido: a martial art which allows you to defeat your enemy without hurting him, unless of course he doesn't know how to breakfall, in which case he will shatter every bone in his body when he lands. Also known as origami with people."

(Source of quote unknown.)

A Japanese budo art that aims for defending yourself and defeating your enemies without causing them lasting injury. Also something Candy and Dev recently got into and even managed 6th kyu in.

One of the hardest parts of aikido is learning to say "uke" (attacker) and "nage" (defender) instead of "uke" and "seme." Note, yaoi background does not help with this art.
