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."

Birthday Dump 

You are hammered drunk and you decide to drop one down, only you find that it happens to be the best damn turd of your young life. It was so good in fact, that you feel as if it was your birthday.

On occasion, the loaf itself refuses to be flushed, enhancing/dampening the birthday effect depending on location.

You are wishing someone happy birthday at a bar, perhaps for their 12:01, and instead of singing the happy birthday song when everyone else is singing it, you yell "take a birthday dump....Jesse Reimer!"

"TAKE A BIRFDAY DUMP" (if ur black)
