Im a ref, I know lots of refs. I was taught by the linesman at todays game, Amato De Luca. He's a FIFA linesman.
Listen, the worst thing to do is start chanting "Fuck the Ref/The Referee's a wanker/Im nlind-Im deaf etc"
The Ref knows this, hears it and will go defensive. Whether you like it or not, you will then not get any boderline calls going for your team. This is simply a bad idea.
Ask a Ref, see what they think.
