It has nothing to do with standing around an ash tray. A barbecue with a full rack of ribs. Or murder. The smoke session I'm referring to is an intense, deomoralizing session of physical activity in which the subject[s] are most often times in trouble for something or they are being evaluated for some illustrious position, such as candidacy for some elite military field. It can be done on a single individual, an individual and his buddy, or a whole group of individuals. Also called a haze session, probably because the subjects don't want to be involved 99% of the time.
