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!

4 day birthday rule

Rule that only applies to your closest bestest friends and gives them the power to bestow their birthday wishes not on your big day but within 4 days of you being born.

E.g. Hey Kate, couldn't wish you on your day but am calling now - I invoke the 4 day birthday rule.

golden square birthday

Similarly to your golden birthday, your golden square birthday is when you turn the square of your birth day.
If you were born on the 6th of the month, your golden square birthday is when you turn 36.
If you were both on the 2nd of the month, your golden square birthday was when you turned 4.
People with high birth day numbers do not get to celebrate their golden square :(

It's my grandma's golden square birthday today! She's turning 81!
