The equivalent of "Bridezilla" for someone celebrating their birthday. The alter ego that appears when a person believes their birthday is the most important day of the year for not only themselves, but for the rest of the world as well. They refuse to settle for anything less than the most extravagant birthday celebration with everyone worshipping their every move. Failure to accomplish this results in everyone suffering the crazy shitstorm of crying, screaming and guilt tripping as this person throws a tantrum over everyone's lack of enthusiasm.
Oh no. I can't make it to Lauren's birthday party. Now I must suffer the wrath of Birthzilla.
