A slam dunk, also dunk or dunk shot, is a type of basketball shot that is performed when a player jumps in the air and manually powers the ball downward through the basket with one or both hands over the rim. This is considered a normal field goal attempt; if successful it is worth two points. Such a shot was known as a "dunk shot" until the term "slam dunk" was coined by Los Angeles Lakers announcer Chick Hearn.
