To tear of a pair of underpants from someone without removing their trousers. Similar to a "wedgie" but the pants are pulled and pulled until something rips (either the pants or the ring piece). A term originating from The Melbage Cup Golfing Society.
Look! There's Bubbs, the great gormless bald headed buffoon. Let's give him a ginching!
