When a male sits down in a seat and accidentally sits on his balls. This is usually accompanied by a shouted expletive and an abrupt jump out of the seat. It happens so quick, it's as if they've bounced off of their balls.
Teacher: "Greg your late, sit down!"
Greg: "Sorry teacher....OW FUCK!"
Teacher: "Greg! Watch your...oh wait was that a ball bounce?"
Greg: "Yes ma'am...sorry."
Greg: "Sorry teacher....OW FUCK!"
Teacher: "Greg! Watch your...oh wait was that a ball bounce?"
Greg: "Yes ma'am...sorry."

When you ask someone if they want to do something with or for you and they say no with a little tude (attitude).
Hey, We are going to a show, do you want to go? or Hey, can you help me move? They say no, you say "what ever makes your balls bounce"
