A pair of knickers so big and unsexy that you could never dream of pulling on a night out. Typically these huge knickers cover your whole belly and your arse cheeks.
Stacey “I’m so excited for this night out, I’ve got my best underwear on, I’m so going to pull”
Caroline “you’ve got no chance with those bellybashers on, they’re hanging!”
A large-sized marble (toy), typically 20mm or more. In Liverpool, a corruption of 'bottle washer'; the combination of spherical glass stopper and rubber washer used to seal a Codd Bottle which was designed specifically for carbonated drinks. Children smashed the bottles to retrieve the marbles.
Ay soft-lad! You can't play a cats-eye with a ordinary marble - you have to play another cats-eye or a bollywasher.
