“Dimitrov skins Moran - deliberately flying to collide there - and it’s got to be another penalty - yes, there’s the whistle!”
-- Ludo Bagman, during the final of the 1994 Quidditch World Cup (GF8)
Skinning is the Quidditch foul of flying to deliberately collide with another player.
During the Quidditch World Cup of 1994 the Irish team was awarded a penalty after an incident of skinning by the Bulgarian side (GF8).
This foul would have been one of the 700 fouls recorded as having been committed during the very first Quidditch World Cup in 1473 (QA6).
Commentary
Etymology
The English word skinning usually refers to removing the hide or skin of a dead creature. In Muggle football (US 'soccer'), "skinning" refers to one player taking the football away from an opposing side's player - or beating them to the ball - using superior speed and ball control skills (Oxford English Dictionary: skin).
