Others believe that lighting three or more cigarettes on the same match will bring on bad luck.
This started in World War I as a basic safety precaution. Some soldiers sitting in the dark on either side of the front decide to have a smoke. When the first one lights his cigarette, the enemy across the field sees the match light. While the second man lights his smoke, the enemy grabs their rifle and takes aim. When the third man lights his, the enemy fires.
