When you are getting it on with somebody anally, totally in the moment enjoying the friction and tightness of a firm asshole and they happen to cum so hard that they literally shit on your balls and completely ruin the moment!
When you visit your doctor cause your peehole stings like a motherfucker and you think it's because of the bacteria from all that butt fucking, only to have the doctor tell you. "No sir... it's not bacteria, it's the Clap!" That is when you have the right to yell "Shitballz!"
