BDBJ 

A BDBJ is when your at a house party and you sneak out the backdoor with a random chick and she gives you oral until your freinds catch you. The term BDBJ only applies if the girl doesnt want anyone to know about the fellatio.

BDBJ 

The standard present of a gf towards her bf on his birthday. Acronym for birthday blowjob. May be initiated as a surprise at any time between midnight and midnight. May be performed by anyone else in case gf is absent or otherwise not able to fulfill her duties.

What? She broke up with you on your birthday? At least she gave you your BDBJ I hope?
