Whoever said they hate mispronounced named, I can't wait to see them butcher "Vadis Odjidja-Ofoe".
Also, "at the end of the day". Doesn't really piss me off, but annoying if overused. But the most important thing to me is spineless referees, as has been mentioned. I've refereed at youth levels since I was 13 and am moving my way up, and I'll try to maintain the most respectful and professional attitude out there- as long as you do the same to me. Want to ask me for clarification on a call? I'll be more than happy to give a quick explanation of my reasoning, if the timing is appropriate. Want to crowd around me? I tell you to back away, and if you're still here in 5 seconds, the card goes out.
Officials needs to be tough professionals, and they'll earn respect, similar to how rugby players treat referees.
