A D4
A D4 is someone from Dublin 4 who thinks they're better than everyone else. They wear designer clothes, fake tan, and act like they're rich just because they live there.
@D4Life: 'I'm not a D4, but I dress like one. I wear Ugg boots and fake tan. I'm just a wannabe.'
Text: 'My D4 friend said I'm a posh failure. I'm not a posh failure. I'm a real failure.'
DM: 'Why do you wear Dubes? They look like Uggs. Are you trying to look like a sailor?'
