The day before your birthday, in which it is perfectly acceptable to go out with your friends, get completely hammered, and act like a fool in celebration. This day is in conjunction with Booty Day, which is the day after your birthday.

Titty Day (4/22) is the only day of the year in which it is required girls show some sort of cleavage in festively celebrating breasts nation-wide. Although the origins are unknown, many speculate Titty Day got its start in the late 1990s, at a South Florida High School attempting to to start a national craze. Whatever the case, Titty Day is celebrated in many locations across the US.
