Get the Sell outs mug.
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 Out mug.
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.

Sell out does not mean a band is popular...It means a band that once may have been decent has changed it's style to suit the pop media and therefor makes loads of cash
new found glory...blink 182...good charlotte...and every other shitty punk band whos singers have voices like they are 5 and don't challenge themselves to sound differnet.
Get the sell out mug.
A musian or musical group that switches from their usuall sound just to be more radio-friendly. It can also mean someone who is too popular for their own good.
Eminem is a great example of a sell-out.
