A sport. The rapid movement of the male gonads in a vertical rigorous motion against the bark of a tree. If your balls explode, you lose. But if the tree bark comes off you win.

A sport invented in 2003 involving the gonads of the male sex, where he (e.g. the jackass) must reciprocate his balls up and down the rough bark of a tree (pref. maple).
If the man loses (as in, his balls fall off), then he must seek emergency treatment and possibly a sex change.
