A dumb punk rock mentality that basically states that if a band gets a certain large number of fans and become more popular within the world as a whole, they have gone too far, past the "popularity" line and fallen into the vanity of fame. They've become too good for the fans and aren't worth listening to anymore. However, the only way a band becomes a sell out is because they have fans in the first place. In other words, if a band "sells out," it's the fans fault.
Good Charlotte did not sell out just because they have a large fan base and are on MTV. New Found Glory, Mest, and AFI are on MTV. Did they sell out? No...

Get the sell outmug. 
A band that writes one type of music and gets a large fan base then leaves all of those true fans behind for some dumb scene kids who dont know what music is.

Get the Sell outsmug. Someone or people (normally a band) that forget their morals or principles to sell records. They give off their values for money. Many people say Green Day are not sell outs because they never did anything that they said they wouldn't, but they said they were punk. Punks do not go on MTV. Punks do not go on Top of the Pops. Punks do not sign up to big record lables. Green Day, like other sell outs, rocked when they had souls.
Listen to EMI by The Sex Pistols, true punk who never sold out. Green Day probably think they are better than the Sex Pistols because they played a bigger gig, but what matters is what the true punks think.

Billie Joe: So do we play this Milton Keynes gig or not?
Tre: One moment while I do something wild and zany in an attempt to be amusing.
Mike: How much is it paying?
Billie Joe: Shit loads.
Mike: Hell yeah! Let's do it!
Billie Joe: Don't forget to never stop claiming that we're not sell outs.

Get the Sell Outmug. Someone who betrays trust for the own personal gain at the cost of another(s). Sell outs should be shunned and are loewr than thieves. Also someone named Traci.
