edition of the word D4 to the Dictionary

We are requesting that the word "D4" be added to the Collins English dictionary. The definition of D4 is: Sometimes used as a pejorative adjective to describe an Irish liberal elitist attitude, based on the perceived opinions and characteristics of some residents of this area. D4 is used as a term for posh people, an example being: This place is full of D4's. Another example could be: Wearing them dubes makes you look like a D4. D4 is already used by many people in Dublin, and should be an obvious addition to the dictionary. Please consider adding "D4" to the next edition of the Collins English dictionary.
