In baseball, the baserunners are allowed to advance to the next base at any time the ball is "in play" which includes when the pitcher (vaguely similar to bowler in cricket) is holding the ball.
When a baserunner tries to advance without the ball ever being hit, this is called a "steal."
When the baserunner and batter are coordinating so that the batter will try to hit the ball during a steal, this is called a "hit and run." The idea is that the infielders will be getting in position to get the runner out, so won't be in good position to play a ground-ball hit by the batter.
So consider a play where a batter strikes out, then the baserunner is thrown out trying to advance (a strike-out throw-out double play). If it's a swinging strike, that might be a failed hit and run, but if it's a strikeout looking, then it's almost certainly a failed attempt at a steal (with the minority of the time it being the batter missing the signal for a hit and run).
I should acknowledge that 2 strikes with fewer than 2 outs is not considered a good count to try a hit and run; unless a poor batsman is up next you are often better off having a fresh count with the next batter. On the other hand a hit and run is really only effective when it's a surprise.
