a cigarette or joint is placed in the mouth, or between the teeth, and smoke is inhaled until the joint or cigarette burns as far as possible, often burning the lips of the person attempting to "get kills" on a cigarette or joint. Kills on a cigarette are often offered to a cheap friend who would like to jew your joint.
