Unhappy birthday

For some reason, this has not been defined on urban dictionary until now.

Anyways, if you are looking for the definition. It's self explanatory (The opposite of happy birthday, used as an insult when it is someone's birthday).

Jacob : Today is my birthday! Will you come to my party?
Micah : Absolutely not, and unhappy birthday!
