Oh come on. It's called banter... Get a grip...
I totally agree, what about sometimes when you get 10,000+ singing the referee's a
whistler. Surely any team going to an opposition ground would expect to get abuse off the home crowd. I know sometimes there a bit of a debate about colourful language + kids being at games but, IMO it always been part of the game, just as it has and still is in other sports too.
