I know everyone thinks this is stupid but it’s been a rule forever that you can’t taunt the player, you can gesture to the crowd. It’s unsportsmanlike conduct and it’s mostly designed to stop players from fighting. I’m not even a fan of the ‘too small’ gesture since it’s more of an insult than a celebration.

Yeah it’s entertaining, but i’d rather not have games regularly break into brawls and having players ejected/suspended for fighting
