9.
A sell out. Somebody who comprimises their integrity, morality and principles for money. It is commonly associated with attempts to increase mass appeal or acceptability to mainstream society. A person who does this, as opposed to following the original path they laid out for themself, suffers immediate loss of respect. The term comes from the prime example; Banksy, the UK based graffiti artist who writes of anti-consumerism and then goes on to make himself one of the most commercially successful brand names in the art world.

Perhaps the greatest stencil artist ever he parades his works around Britain quite illegally. He defaces monuments, spray paints animals and generally bugs people off.

5.
A sexual or pseudosexual act of rejection. The rejected partner is woken in the early hours of the morning preferably whilst sleeping on white bedding and subjected to a high-pressure curry fart to the head, permanently silhouetting their shocked expression into the pillow. For a true 'banksy' one must accuse them of not getting the joke afterwards.

Banksy is one of the most famous and possibly the best stencil graffitist ever. He was inspired by Blek le Rat and has been graffiting since a very young age. Almost all of his work is designed to mirror and satire goverment, polotics and modern socioty. He is NOT a sell out, his books were written to promote his issues and to explain his mindset to his fans and all the money he makes from selling signed canvases is well earnt. A true hero of freedom of speech
Hay dude, you seen the Banksy round the back of that Starbucks? Its the sandwhich board monkey!
