Nuts!
Sounds like i've been shot in the Nuts more than my fair share.
(most of it happens when doing running and gunning drills, when you get all shot up)
The worst one i've ever had was when i was at the start box getting ready for a game, there was a 10 second call,
I accidentaly fired my marker directly into the ground and the ball bounced straight back up and caught me square in the left nut. I dropped and then about 5 seconds later got lit up by the other team.
Thinking about that still brings a tear to the eye.
