birthday whore 

Doesn't matter what day her birthday is, a birthday whore sucks up the whole month and makes it her birthday. You begin celebrations on the first of the month and end the festivities 4 am (or whenever the bars close) the last day of the month.

Christine's a birthday whore...she's having her birthday all November long.

birthday sex 

Obligation-free sex which happens on or around someone's birthday. Usually initiated by the birthday boy/girl's partner, and involving a mix of acts which more favour the birthday boy/girl's preferences.

The usual rules of reciprocation and mutual pleasure are temporarily suspended, and the birthday girl/boy is considered free to cum whenever and wherever the fuck they please.

Nah, can't come out tonight... I'm hoping for birthday sex.

Birthday Luck 

On your birthday, a nuclear explosion of luck happens inside you. It causes you to have the ability to do anything. That attractive guy/girl you like? You're dating. That proposal you were worried about showing your boss? Got you a promotion. Daft Punk? They're playing at your house.

Guy 1: So wait, you're calling in sick today to take Caroline to the Usher concert? Nice!

Guy 2: Wrong. Usher invited me and my beautiful lady-friend to personally chill with him today.

Guy 1: Damn! How the hell did you pull that off?

Guy 2: Birthday Luck, man!

Birthday Boobies 

The act of sending pictures of boobies, naked or clothed, to a birthday boy or girl.

This is a relatively new tradition, and in practice, it is more often men sending men pictures of their own chest, or men convincing random girls to send pictures of their cleavage to their friend on his birthday. However, the act was originally conceived to span an influx of casual acquaintances of the opposite sex to send you risque pictures.

Example 1:
Man your phone has been blowing up all day. I hope at least some of them are Birthday Boobies pics.

Well, I did get these from your sister...

Example 2:
How did you get pictures of Lisa's tits!

Birthday Boobies!

Example 3:
Andy really came through at the bar last night. He must have had over 40 girls send me birthday boobies. At least a dozen of them showed nipple.
