This dismissal happens when the batter knocks their stumps over while playing a shot or avoiding a delivery.
This can be with the bat or with the body.
It often happens when a batsman steps back too far playing a difficult delivery and treads on the wicket.
Kevin Pietersen was once out "hit wicket" when the chinstrap of his helmet broke and the helmet hit the wicket after it fell off.
The bowler gets the credit for the wicket.
