Bum Monster

When a girl wears really tight trousers or jogging bottoms that ride up the crack of their ass. Women of a larger frame are more likely to be visited by the Bum Monster. In extreme cases the whole of the garment can be sucked up into the body.

The 'Bukmonster' is a name given to a sneaky Japanese pervert who derives pleasure from publicly masturbating- whilst sneaking up on clueless girls and ejaculating on them, usually aiming for their faces.

Girl A: 'Oh Shit run it's the bukmonster!'
