Compromising your integrity, usually for money. Its that simple. This word is mostly used to describe bands that go mainstream.
Green Day aren't sellouts because despite their recent popularity, they never changed their sound. They were just never very good...

1. A band that changes it's style for stupid teenybopper girls and getting more money, even though they already have tons of it.

2. A word used by teenaged wannabe goths/punks to sound hardcore. Those people usually come up with bullshit reasons like "WE DON'T WANT TO CONFORM TO SOCIETY" and say "THEY BECAME POPULAR AND STARTED TO SUCK".
1. Good Charlotte, Maroon 5, Blink 182.

2. "OMG OMG I WANT TO SOUND HARDCORE I CRAVE TO BE HARDCORE SO I SAY THEY ARE A SELL OUT".
