Check out this Boston mother who was none too pleased with a referee’s handling of a hockey brawl between two youth hockey teams. She walks right onto the ice to argue with the referee and shake her finger at him multiple times.

Let this clip be a lesson to all youth sports parents out there — never walk onto the field of play to defend your child. You’ll get your kid killed — socially.

Who wants to be teammates with the kid with a mom who walks out on the ice? No one. Everyone wants to be friends with the kid who’s mother brings Juicy Juice and orange slices and goes away every weekend, leaving her son home alone with the liquor cabinet unlocked.

This mom leaves the liquor cabinet unlocked because all the bottles are empty, it’s contents poured into mom’s Gatorade bottle.
