Comes from Bloodshot Bill:

“”Most people who see me on the street see my pompadour and just call me Elvis. I don’t think I look anything like Elvis but that’s all they know. Most people don’t know anything about rockabilly, let alone psychobilly. When people see me play, they wonder how I invented this type of music – it’s crazy how little people know about music outside of Limp Bizkit or some shit. Psychobilly is just good-time music that uses traditonal rockabilly and can get really crazy. If it’s not fun and really crazy, then it just isn’t psychobilly.”
