It's weird, because this song seems straight forward yet has some very ironic undertones. I think the singer is admitting his true hard-headedness, but also saying that because he owns it no one has the right to put him down for it. So he's partially exaggerating his own faults and sarcastically supporting the poor choices of his so-called friends that give him such a hard time, to demonstrate that he's not such a bad guy, even if he's flawed.
