The act of using a bottle as an anal alcohol injector. An empty glass bottle (usually a
beer bottle) is lubricated at the neck (usually with vaseline) and a quantity of
hard licor is poured into the bottle. The end of the bottle is then inserted into the anus, and the person does a
head-stand, or inclines the body, so that the alcohol flows into the rectum, where it will be absorbed more quickly, and effectively.
