Taking shirts from the washer to the dryer, one was twisted around itself. Instead of undoing it by hand, I figured it would be quicker and simpler to just hold it at chest height and shake it loose.
The bottom end of the wet shirt came free on the second whip-like shake and whipped me right in the stones. That's right, I basically wet-towel snapped myself. In the balls.
hurt like a MFer, luckily no scar. there was a lot of blood though. i most certainly did not enjoy it.
