When a man or woman is sitting on the toilet taking a number 2, when the time comes to wipe, they happen to get a little bit of feces on the wiping hand.
I just foul balled at work. I took off my coat too.. I had to wash my hands and go back to get my coat. I hope the guy in the stall next to me didn't notice.

A sexual act where the guy asks a girl to teabag him while knowing that he hasn't washed his scrotal sack for an extended period of time (at least 5 days). The woman begins to teabag the man and gets a mouthful of ballsweat and whatever else may have grown or collected on the scrotum.
Gerald hadn't washed for weeks. At a party, Jenna took him to a back room with the intentions of a teabag. She ended up with a foul ball, and quite a taste in her mouth.

When you are pooping and the length of your turd would cause you to normally have to raise up off of it, but it breaks and falls forward hitting your testicles.

After playing a baseball game or any time your balls get UNBEARABLY stinky from the excerise. After the intensive physical activity you decide that you need a BJ or your nuts sucked on. When the girl goes down to suck your nuts she will cough or throw up from the smell and while she is coughing you proceed to yell FOUL BALLS!!!!!
girl: "O I want to suck your balls."
guy: " I am very okay with you sucking on my testicles right now."
girl: "I'm sucking your nuts and cough cough they are smelly"
guy: "FOUL BALLS!!!!!!!"

Richard thought he had a hernia but it actually turned out to be a foul ball. They popped that sucker out and dropped a new superball in his sack.
