When fans leave the stadium before the end of a game when their team is losing. Particularly bad form if it's a kids' game.

When everyone leaves the stadium at half time because their team is losing so badly. Especially effective term if the losing team makes a huge come-back and wins. Can also be used to refer to leaving a party or concert early just because it doesn't meet your initial expectations then hearing the next morning that it turned out great.
