A person who thinks they're cool, but they're just a fake poser. Everyone in Cork knows they're nothing but a joke. If they do something super lame, you yell 'baaage' like it's the end of the world.
'He tried to rap in the bus. Baaage!'
'She called herself a rockstar. Baaage!'
'He tried to flirt with my sister. Baaage!'
