the process of releasing smoke from one's mouth, only to be inhaled through the nose immediately there after. If done properly, there will be essentially no excess smoke that is blown out.
Initially, learning the move is difficult for some. It may take a few tries. One should no force it. take one long hit of whatever it is that you are smoking (it easier with tobacco than any other "illicit" substance), then open your mouth and allow the smoke to escape, naturally. you DO NOT forcefully blow the smoke out of your lungs. once the smoke is coming out (by itself), all you have to do is inhale through your nose, and the move has been completed.
