A 21st birthday party where the birthday-person is given a thick paper sign. The front side of the sign is designed to include things iconic to the person alongside with the name of the party. The back side has a handwritten list of 21 dares, which are usually drinking or dancing related. Dares are meant to be completed that night, typically at a bar. Sign nights also typically involve custom stickers, with a design that embarrasses the birthday-person, being given away to attendees to commemorate the celebration. Sign nights typically have a theme which can be reinforced through decorations and attendee outfits. Sign nights were popularized by students at the University of Florida and then spread across the southeast.
