Kung-Football
Kicking/using your feet to keep a ball from bouncing up off the ground and hitting you. Especially useful for if you want to have kids some day. Poor testacles :(
I used Kung-Football to protect my nards. Funny thing Kung-Fu would be invited in Asia. We have a bigger more sensitive testacle problem out west. Oh well, at least I kept my nuts. and semen. and sperm.
