schadenfreude bone

A new name for the "funny" bone, as it's really not so funny when it happens to you. But when it happens to someone else, it sparks feelings of schadenfreude.

*buddy smacks his humerus while working*
buddy: Aw, frig, I can't even feel my arm!
guy: Haha, hit your schadenfreude bone, did we? Sooo glad I'm not you.
