It's when a team goes on the fast-break, and a defender BEHIND the offensive player with the ball fouls him before he can get to the basket. The player gets 2 free throws and his team also retains the ball.
This rule is implemented because:
A) The team would've almost certainly had two points had the defender not fouled from behind.
B) Often the foul is out of frustration and commonly leads to injury, so the league wants to discourage it.
