There are a few ways.
Bin festery is one.
Flouncing is another.
Starting a thread about a player, saying they are crap and "what do they do?" before the same players goes on to become a star for us.
Or simply getting something wrong, like typing "were loose" instead of "we'll lose" or asking whether the club shop opens on Christmas Morning leading to pages of ridicule to follow (not that I've ever read the latter, but it's only a matter of time before someone asks).
Or leaving a game at half time when we are 2-0 down and posting how shit we are before the game has finished.
