d4
A d4 is a rich kid from Dublin who thinks they're fancy because they wear Abercrombie and American Eagle and think they know what being posh means.
My d4 cousin said, 'I wear Abercrombie because I'm posh.'
D4 girl said, 'I only wear American Eagle because I'm fancy.'
D4 boy said, 'I'm not just rich, I'm posh and I wear Abercrombie.'
