What is double zero?

Double zero refers to a numerical value of 0 which appears twice consecutively. It can also refer to a clothing size, specifically a women's size 00, which is smaller than a regular size 0. In the game of roulette, double zero refers to a pocket on the wheel that contains the number 00 in addition to the standard 0. This increases the house edge and decreases the player's chances of winning. Double zero can also be used as slang to describe someone who is very attractive, such as "she's a double zero."
