Heard a ridiculous one when playing for my uni side yesterday morning. Opposition full back has the ball, his winger was surrounded by 2 of our boys. Needless to say this guy had a pretty poor touch, yet was screaming 'hit me down the line' to his fullback. He wasn't making any attempt to run in behind, instead he just stood there like a fecking mannequin roaring 'down the line, hit me now'.. Which of course his full back did only to find that the winger's shit touch turned possession over to us, which nearly led to us scoring. He was at this all game.
Another one is when a corner is taken, you clear it and everyone shouts in unison 'Out we go boys' to be dealt with a moron (I've noticed these tend to be full backs for some reason) who manages to not hear the shout and plays half their team on when the ball inevitably gets pumped back in again.
Another shit one is when the keeper is about to take a goal kick, defence has pushed out a good 20 yards...keeper takes his time, surveying his options and then suddenly roars 'WHO WANTS IT!', which automatically leads to him panicking (these tend to go hand in hand) and kicking the ball either short to one of the centre halves who are instantly under pressure or straight into their midfield who win the ball 30 yards from goal and score.
