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.
