a loud proclamation said by someone when it is their birthday, usually highlighted by said someone forcing a door open with their foot
It was quiet in the house, when all of a sudden Steve busted the door open and yelled :

"it's my birthday NIGGA."

Everyone immediately gave Steve all their money from their respective wallets.
