Its all part of casual cigarette games.
There are actually several variations on packing cigs.
The full pack pack can consist of a single, forceful packing blow to the the heel of the hand. This is seems to be a rarity among dedicated packers though. A die hard packer will tell you that the one swing method will not do much to effect the tobacco “density” in the cigs.
More common is the multi swing pack action. Informal studies show that there is an average of 6 or so swings made in rapid succession. Results vary as to how packed the cigs will be or if they will be deformed at the ends among these solo packers.
Among active participants of casual cigarette players, there is typically a designated “packing master” among a group of smokers. For some reason, this person is able to pack a pack of smokes so that there is upwards of a quarter of an inch of empty paper at the end of the cigarette with no discernable loss of tobacco form the cigarette or deformation of the individual cigarettes. There is a level of “packer” pride and intense competition among “packing masters” as to who can pack the cigarettes the best.
Superstitious, or really bored, smokers will incorporate a game into the packing action of the cigarettes. A “guru pack master” will ask the the owner of the new pack of cigarettes for a number. The pack master will employ the packing action until the number of packing strikes equal the number given by the smoker. True packing gurus will open the pack for the smoker and initiate the “lucky cigarette” switch out. This is where one cigarette from the pack is removed and turned over. There is two fold reason for this action by the guru packer, one to check that his pack action was successful, and two to attempt to imbue the lucky cigarette with mystical powers of luck and good fortune.
Other packing variations.
The single cigarette packing action.
This method is typically employed by more anal retentive smokers in search of the perfect pack for each individual cigarette in the pack. Normal methodology involves “bouncing” the butt of the cigarette against the side of a lighter. Some single cig packers can bounce the cigarette upwards of 20 times to obtain the perfect individual packing action.
The individual cigarette pack is also heavily employed in times of nervous conversation, such as meeting an attractive memeber of the opposite sex in a bar. Subconciously, it is used to broadcast the fact that the person is a smoker. More over, it is utilized to keep the hands busy so they do not leap out and attach themselves to the attractive persons bumpy bits thereby potentially terminating the initial meeting with the attractive person rather abruptly.
There are urban legends of “packing mystics” that can pack an entire carton of cigarettes in one swing. The Casual Cigarette Gaming Commission will pay a bounty of $50,000 for information leading to the finding of one these “packing mystics” to study their mystical cigarette packing prowess.
