When you are going down on a girl and your munching down that sweet pussy, the act of custard creaming is when you crunch down the outa vaginal flap (like the biscuit) and then make your way to the centre where you get the cream.
I've been custard creaming girls 24/7
When one's bollocks are busted in a painful fashion. Can also describe an idiot, a nonce or your general Kool Kid
Oi, you bollock buster, get over yourself you self obsessed, weed taking, girl flirting fuckface
