The act of changing yourself, your intrests, or everything about you to fit the majority. This can be applied to alot of things. Such as a good friend leaving you out to dry for personnal gains, or a music group changing their own style to sell records.

To abandon what is really you just so you can be "cool" in the eyes of everyone else.
My friends (sell outs): Hey lets go dress up in pink Polos and short khaki shorts and sperries and spend all our money on crown royal and take Daddy's BMW and go hang out with all those real rich preppy kids from school so we can be awesome and just maybe get laid from a couple of town bikes

Me: Have fun

People who jump on the bandwagon. Who listen to a song on the radio, decide they like it, and then suddenly call themselves punk. Where were you ten years ago, when we were skating around listening to punk rock. As i recall, you told us that our music s*#ked. One who can't think for themselves.
Punk Rock is dead, you F#*king Sell Out.

Used by kids who want to sound "hardcore" when a band they like gets popular. Suddenly the band sucks because they're popular, so how the fuck did they got popular in the first place if they suck.
Dude, like Good Charlotte so sold out by going to MTV.
No, they've always blown cock.
