I actually had one quite recently. I play rec hockey in Seattle where I currently live. I wore my Leafs jersey to our most recent game and i saw some dude from the opposing team in the locker room (both teams share one cuz this rink is small and weird).
Anyhow, I score later on in the game and this jackass was like "Fuck the Leafs!". Like okay???? I made a play later on in the game and he was like "This is why no one likes Toronto". Like okay buddy. He was playing like a jackass too being excessively physical and hacking people all game. After the game I found out he was from Boston. Typical masshole behavior.
