birthday motorboating 

A practice of shaking your mouth back and forth over the lucky birthday girl's (or boy's) breasts, an equivalent amount of times to their age.

Darn, it took forever to finish Barb' birthday motorboating because she is now 88 years old. My lips are numb.

Birthday After Party 

The after party of a birthday including the birthday participant and the birthday participants friends. Usually an invitation to this kind of party means that you are a close friend/lover of the opposite sex and are most likely in for a long night. Many a time have boys received invitations to after birthday parties and have come out different men, due to the wild/craziness of the sex.

Papa Johns: Yo steve, how was the birthday party?
Steve: The party was insane, I was invited to the birthday after party and now I am a changed man.
