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.
