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!!!!!!!"
