The high five is a hand gesture that occurs when two people simultaneously raise one hand each, about head-high, and push, slide, or slap the flat of their palm against the flat palm of the other person. The gesture is often preceded verbally by a phrase like “Give me five”, “High five”, or “Up high.” Its meaning varies with the context of use but can include as a greeting, congratulations, or celebration. –Wikipida
