Butt Chug

Inserting an alcoholic beverage into your anus either through a bottle, but preferably a beer bong.

A method of drinking alcohol that involves shoving a tube up your rectum, and then feeding booze through said tube into your ass, which somehow manages to give you a stronger and quicker buzz then drinking it normally. Often seen as a staple amongst drunken fraternity tomfoolery

Similar to a beer bong, but the consumption of beer is rectally, using a funnel and tube to administer the beer as an enema. The primary purpose of butt chugging as opposed to drinking beer is that alcohol administered as an enema has 3x the effect of alcohol taken orally.

Watering plants by letting them absorb water from the bottom.

An alcohol enema, also known colloquially as butt-chugging, is the act of introducing alcohol into the rectum and colon via the anus.

The act of ingesting alcohol through ones rectum. The idea is to increase the alcohol's effect and the speed with which one becomes intoxicated.

Having an intoxicant enema, the main purpose of which is to bypass the vomiting reflex, though it also causes the active ingredients to be absorbed faster, for more fun and greater tissue damage. Apparently Mayan priests used to do this with mixtures of alcohol and powerful tropical hallucinogens, and the ones who survived often had strange insights, now sadly lost to us.
