A player, usually in Primary School soccer, where the offside rule doesn't apply, who stands as close to the goalline as possible and does either of two things :-
1. Get his foot onto a shot from a fellow teammate in order to claim the goal
2. Hangs around waiting for the ball to rebound off the post or be saved by the 'keeper in order to knock it in from 2 yards.
The most Cheesy of all Dompers is adept at doing both.

I wouldn't play with Nigel. He's a bit of a cheesy domper.
