A scene jumper is not a poser. A scene jumper is active in more than one music scene. If you were to reject a certain type of music in order to avoid being called a scene jumper that would make you a poser.Liking more than one type of music and attending shows i.e being an active part of that scene
as well as another scene makes you a scene jumper. There's nothing wrong with it. It's just being versatile.
Kid One- Likes Pop, tells friends he likes hardcore when he doesn't, goes to shows and doesn't like the music, dresses what he thinks he should = Poser
Teen Two- Likes Rap & Likes Screamo, goes to rap and screamo shows and concerts, is honest with his friends he likes both kinds of music= Scene Jumper
Teen Three- Likes Rap Only, Dresses "scene", goes to rap shows = Loyal to rap music, not a poser not a scene jumper
I like all kinds of music and go to all kinds of shows. I'm a scene jumper. Don't like it? Oh well...
