Birthday Psychosis 

When it's a person's birthday and they announce it every 5 minutes on Facebook for friends to wish them a happy birthday even though everyone already knows. Once their friends are suckered into sending birthday wishes - they then ask for more without saying thank you, leaving everyone amazed and moderately disgusted. Slight variation of attention whore

Birthday brat: HEY EVERYONE ITS MY BIRTHDAY TODAY WISH ME HAPPY BIRTHDAY

Thoughtful Friend: HAPPY BIRTHDAY

Birthday Brat replies: WHERE'S MY GIFT??????????????

Thoughtful friend messages everyone else secretly: OMG!! He has Birthday Psychosis!

Birthday Special 

A birthday special is when, on his birthday, a man is having sex, and before climax, places a birthday candle in his partner's mouth, lights it, and finishes on their face. The man can also try to put out the candle with his semen, making a "blow out the candle" feel, and/or have his partner hum happy birthday as they receive his load.

Man 1: Hey, happy birthday, bro! Got any special plans for tonight?

Man 2: Yeah, I'm gonna get a birthday special from my girlfriend.

Man 1: That's awesome, just make sure the wax doesn't burn her lips.
