Gallie
A Gallie is someone who thinks they're the cat's meow, but they're really just a sad kid in a cool outfit who doesn't know what 'cool' even means.
Gallie: 'I'm in, I'm out, and I'm the best at it.'
Gallie: 'I'm the trendsetter and you're just here to watch.'
Gallie: 'I'm the style icon and you're just here to be jealous.'
