A area in dublin 16 (knocklyon, rathfarnham etc.) where it is filled with posh snobs that are loaded with cash.
Just like actual d4's
they hang out at dundrum where they spend all of their daddy's money in shops like tommy hilfiger, harvey nichols etc.
They are always seen wearin abercrombie, american eagle and hollisters hoodies, aswell as the girls sporting the usual uggs
and the boys wearing brown dubes
They ALL love rugby and attend the local discos every few weeks (judes, wesley). here they score
other people and most likely get drunk.
d4's or d4 squared have a certain way of talking.
For example, instead of using the word 'right' they say roysh
and "oh my god" will become OMG!
