Self righteous, ray ban wearing, hair slicking, elitists in a music scene, who see themselves as superior to everyone around them. Generally, they don't play in bands, or if they did it was several years ago and they are resting on the laurels of their mediocre success. See everyone around them as inferior and fake, despite the likelihood that the people they are targeting are more genuine than the Post-Hardcore Kid. The kind of pompous shit heads that taint music scenes.
You don't like (insert band here) you're a fucking poser
