it's a bit like the bumsniffer one used by people to slur people who follow Rugby league.
Not quite, it's the rugby codes in general and more light-hearted.
The other expression has died out quickly with political correctness and I'd thought a mod wouldn't mention it at all.
The only expression that annoys me is when people say "football" in mixed company or in the media.
It doesn't take much effort to put an adjective before the word or even simpler to mention the specific league
as in AFL,NRL, EPL or whatever RU is called these days.
