Get the bum blastmug. Horrific act of gross sexual violence, as featured in "murder trainer" videogame Manhunt, and as a result in playgrounds across the United Kingdom.
"Manhunt is a very violent game - it's a game that features people getting bludgeoned to death, people getting bummed in the gob, people getting garrotted..." - a videogames "expert".

Get the bummed in the gobmug. To un-intentionally show you bum. Usually only the top part is revealed when bending down. Or if you’re a builder of some description you will already be wearing loosely fitting pants that assist in revealing your bum crack.
I was walking along the street when I saw two moons looking at me. The fattest builder was showing every one his bum crack. To which I shouted out say no to crack!
