I find it really offensive when any swearing is yelled out at game's of football. I use foul language more than anyone when I'm with my mates, but when there are children around at the footy, I find it completely inappropriate. Some Storm supporters are true ferals.
i'm happy to swear if I can't see any kids in the vicinity. I know this doesn't always mean that kids won't be hearing me, but I at least try to stick to simple words such as "wanker", "dick flop", "**** house". I've never claimed to be a beacon of decency though.
