A way to say 'Bravo!' or 'Good job!' by
slapping someone's hand in the air; to congratulate someone
1) Nice shot! High five, dude !
2) High fives all around on the excellent presentation at the meeting !
There are five fingers on your hand, and
you lift your hand high into the air to give a 'high five'. This is a
common gesture first used by African-American basketball players and now
used by many people in a variety of contexts. You can also give a 'low
