The way you wish someone a happy birthday on facebook if you don't like them, sometimes in hopes to stir up a fb fight.

When you have a friend on Facebook or something that you don't really know that well, and it's his/her birthday, you say "hbd" instead of saying "Happy Birthday!"
Person 1 : Hey, at the side of my Facebook it says its John's Birthday. I don't even talk to him, but he goes to my school. But I'll just say happy birthday anyway.

Person 1 : hbd
