Surprise Birthday 

The act of shoving your fist into a late pregnant lady and pulling the fetus out.

I really wanted Jim to be born on 4/20, so I gave him a surprise birthday.

Surprise Birthday Party

A very daring sex move; occurs when a male receives oral sex and fails to notify his partner of his impending orgasm, during the course of his shenanigans, the male discretely pulls out a happy birthday hat, confetti, and noisemaker. At climax the male then proceeds to blow into the noisemaker, aim his load on his partner's face, yell surprise and throw the confetti in the air. You get extra points if you get the confetti to stay on your partner's face with your splooge glue.

The other day while Joe and I were ramming I got a Surprise Birthday Party !

Japanese Birthday Surprise 

Given on someone's birthday, this involves tying down the recipient and attacking them with tentacles shaped like giant penises, followed by urinating on them. While this may sound unpleasant to the average person, there are at least 20 different hentai mangas devoted to this very subject.

Geoff: Happy 22nd, Jamie! Now it's time for your Japanese Birthday Surprise!

Jamie: Japa-what? What the hell are you... oh my god AGGHHHHHHHHH

(screams of agony are heard)

Birthday Surprise 

A sexual maneuver in which, on the recipient's birthday, the birthday person bends over in the dark. A large black candle is then carried in and "Happy Birthday" is sung. As the song concludes, the candle is lit and inserted into the ass of the person. The candle is thrust into the ass, once for each year of the person's age. At this time "Are you 1? Are you 2?..." is chanted. The candle can then be removed.

"Yeah, it was Debbie's birthday last weekend...We gave her a Birthday Surprise, she couldn't walk right for a week."

the birthday surprise 

When two guys are double penetrating a girls vagina the guy who is doing her doggy style slips out and sticks it in her ass. But you have to have a camera to see her face.

Her face is so funny when she gets the birthday surprise.

Harry Belafonte Birthday Surprise

A Harry Belafonte birthday surprise is when a man inserts his penis into a birthday cake and farts, or 'queefs', out of his' penis into the cake, leaving the expelled gas in the cake.
