Most def heads tend to be 13-18 years old, and have very little (one or two years) expirence playing their instrument (guitar, bass, drums, ect.). Most def heads are self-taught players and belive they do not need any form of proper lessons or music theory because they are musical geniuses right out of their mother's vagina. Some def heads are aware that they suck but dont have the balls to admit it. Def heads usually form really shitty bands with other def heads. A def head doesnt play music with any passion or feeling and only plays for money, fame, and sex.
Franklin The Noob Guitarist: "Man I'm such a beast at guitar! Nobody can touch me!" (plays really shitty genric punk riff)
Yngwie Malmsteen: "You're a fucking def head! That sounded like shit! Step aside and let papa show you how its done!" (plays mind blowing solo)
