When you go to the US, someone often says "give me five". What should you do? Do not get five dollars from your pocket! It will make them laugh! They are not asking for your money, but your fingers. In the US, "give me five" or "give me the high five" is a popular gesture(手势). You can see it often in movies or on TV. It means hitting each other's right hands together.
People do it when they meet for the first time or something happy happens(发生). For example, when a student gets good grades in tests. If a football team wins a game, the players will give the high five to everyone around tocelebrate.
This gesture may come from the old Roman gesture of raising(举起) the right arm for the king. This showed the person raising his arm did not have a sword(宝剑) in his hand.
Why not try to give the high five to your friends?
