That just reminds me, I went to a small private college and my friends and I would print the visitors team roster off for basketball games and taunt them by name. It was always in good fun and we'd even get them laughing at the stuff we said. A lot of our main targets at a given game would come over to us after, win or lose and shoot the shit.
We did something similar way back when. We were on a road trip and it just so happened that our home hockey team was in the same place for a away game. It was a neutral game (in order to keep costs for the league down as it was starting, they had 3 teams travel and play each other over 3 days so there was always a neutral game). We gave the goalie so much grief, the local team gave us a two for one tickets + beer to come back the next day to heckle the goalie some more.
In our drunkeness, I'm sure we crossed the line a few times but I don't think it was overly personal (small hockey community in this country so everyone knows everyone). Our chant to the goalie was "ffffffuuuuunnnneeelllll!!!!!" (because unlike a sieve, everything goes through a funnel).
All the teams would come over after and have a drink with us.
