A night, usually Monday, where a bunch of 30 year olds pretend they are 11 and try to fill up their football sticker books. Also they bust out some old school things like 8bit nintendo, kool aid, and talk about being a kid.
Sorry Gertrude, we can't go out tonight. Its stickerbook night and I have an itch to play paperboy.
