Mitchenmanjensen prefaced their response by saying their friend is "not really that big an asshole," but Redditors begged to differ.
"He'd grab stuff out of my lunchbox or off of my lunch tray if I wasn't paying attention," they wrote. "One day he happened to be behind me as we were driving to school, and he thought it would be funny to tailgate really close the entire drive. He also thought that it was hilarious to go around 'sack tapping' everyone, every single day. Sometimes it's just dumb sh*t that adds up."
Mitchenmanjensen is not the only one to see sack tapping—a slang term for smacking someone in the balls—as a friendship deal-breaker.
"I had a friend who thought it would be funny to sack tap people until he did it to me and I broke his nose with the spine of a chemistry book," said melloboi23. "I don't think he sack taps anymore."
