Please do tell me the difference.
It's simple. As I say to players when I referee at a weekend...
...If you blaze a sitter over and I hear you say to yourself "oh **** sake!" or "you twat!" it's different to...
..."you ****ing old ****" or "you ****ing useless ****er". That's then aimed at someone, and isn't one word either.
It's then a tirade against an individual. If that was said to anyone loudly, be it fan, manager or fellow player - I'd put a discipline report in.
The first one, I would overhear and ignore, as I believe the circumstances are different. If it became excessive, continuous, or loud, I'd have a word.
