When grown-ups play sports, there are people called umpires who watch the game and make sure everyone follows the rules. Sometimes, if someone doesn't agree with a call the umpire makes, they might get really mad and say mean things to the umpire. This is called umpire abuse. It can hurt the umpire's feelings and make them feel like they don't want to do their job anymore. It's important to always treat the umpires with kindness and respect, even if we don't agree with their decisions.
