The picture that you change your profile picture to on a social network for your birthday. This is usually done the day before your birthday because it will be seen by more people than normal as they wish you a generic "happy birthday."
Friend: Come on, we're going to be late!
FB User: Almost done! I just need to change my picture to my birthday profile picture so that people think I'm fun and popular when they wish me a happy birthday!
