When a player successfully wins a pot with the worst hand. "Stealing the blinds" refers to a player raising with a marginal hand from late position when no-one has yet entered the pot. This is done in the hope that the two players in the blind position seats will fold.
A player may successfully 'steal the pot' by executing a bluff which does not get called. 'Stealing the blinds' refers to a raise pre-flop, usually from the button, purely with the intent of pressuring the players in the 'blinds' to fold, and therefore pick up the pot.
In poker, the term steal is often used as merely a synonym for bluff, but there is a more specific use of the term which is also called an "ante steal" or "blind steal" (depending on whether the game being played uses antes or blinds).
In basketball, a steal occurs when a defensive player legally gains control of the ball from an offensive player. This can be done by deflecting and controlling, catching, or batting (to a teammate) a pass or dribble of an offensive player. The defender must not touch the offensive player's hands or otherwise a foul is called.
