My lad is big into his rugby league & plays (between injuries) for a local team. You think rugby is a game for thugs but they have a saying that "Rugby is a game for hooligans which is played by gentlemen. Cricket is a game for gentlemen which is played by hooligans".
Another saying is "what happens on the pitch stays on the pitch", which goes a long way towards any bad feelings not following on after the game. They also enjoy a lot of what is called "sledging" which I'm sure happens in all team sports. All through a game they are slagging each other off attempting to rile the other team, my personal favourite is "Hey up mate, long time no see, how's your missus . . . & my kids"
Most games I've watched have been multi-cultural, my lads team have just the one BIG black dude whose nickname is MEAT. Asking my lad if he ever gets the N word sledged at him my lad told me he does occasionally, he won't react in any way but the fullbacks know how to break ribs & someone isn't going to work to tomorrow.
