A big-headed, self-centered, smelly, overgrown baby who thinks they're the best at everything, even though they're clearly the worst. They also like to stare at red-haired guitar players like they're the only one who matters.

'He's so J3, he tried to sing at a concert and ruined the whole song.'
'He's a J3, and he still thinks he's better than the band.'
