D4s
A D4 is someone who isn't from Dublin 4 but acts like they are. They wear designer clothes and think they're better than everyone.
She said she's a D4 just because she wears Ugg boots and fake tan. I told her to go back to her rugby club.
He said he's a D4 because he goes to The Wezz. I told him he's not cool.
She says she's a D4, but she can't even spell 'Dublin 4.'
