　　Hand Gesture 5: The A-Ok. Photo Credits: Midweekpost

　　The A-OK sign is an upgrade to the thumbs-up sign. It's used for the same purpose: to show approval or agreement, when you're excited for something. The A-OK sign is made with the forefinger and the thumb meeting at their tips to form an O, while the other fingers are extended. People use this to show enthusiasm for something, like when on vacation and about to go surfing in Hawaii, or when about to get on Space Mountain at Disney World. If you're male and over 18, please do not sport this sign while looking shadily at Snow White. Or her seven dwarves, for that matter.
