Brummie Birthday Cake 

The act of defecating inside a woman's vagina, ejaculating one's load upon the vagina and finally putting out a cigar or cigarette on top of the mixture of dung and semen. All this is to be done on a very special occasion; predominantly on a birthday.

Oi mate, did you see my post on facebook last night?

Nah mate, that were a Brummie Birthday Cake.

The Birthday Cake 

Having sex with a girl from behind, and finishing on her ass. After you've finished you use a rubber spatula to evenly distribute the cum on her butt cheeks, as if it were icing on a cake. When this is complete you may stick a candle in her butt hole and light it. Finish off by putting on a birthday party hat and you have successfully completed The Birthday Cake.

"Dude, I gave Steph the birthday cake last night!"

"Oh that's nice of you dude, was it red velvet or...?"

"No dude, I came on her butt and smeared it with a spatula."

first birthday cake 

This cake is the dried and combined juices of both parents when a successful conception has occurred. It can be found anywhere and is not recommended for eating.

Two hours after confirmation that she was pregnant, Ashley finally washed her sheets and got rid of the first birthday cake.
