Slum-dunk is jumping up and putting the ball in the net with a lot of force. But sometimes slum dunks are quite dangerous. Especially when the playground looks quite old and the players are not professional. Like in this video - young basketball player wanted to make slum-dunk, but instead he overturned the basket. Unfortunately the accident was not avoided. He was really lucky that he did not hurt himself. After this situation he got up like nothing happened.
