To be honest, I think it's funny when the away fans sing the usual 'where were you when you were sh*t' chant. They only show themselves up when every City fan within 3 blocks of them turns towards them and claps, jeers, whistles etc.
What irritates me is when clubs bounce to a tune. Chelsea a few weeks back. 'We're gonna bounce in a minute' - pathetic, leave it to the masters, the foreigners. Also Arsenal with that Nasri song. That annoyed me because it was just so pathetic that only a few hundred of them bothered. Even their own fans knew it was drastic.
