Noun.

A process used by the very frugal as a way to bypass the liver and inject achohol as directly as possible into the blood stream.

The subject lays on their back and proceeds to roll on to the back of their neck so that their asshole is pointing directly in the air. The asshole is then gaped and alchohol is poured directly into the anus. The alchohol is then absorded through the rectal wall, directly into the blood stream.

The safeguarding of Earth and other worlds from biological cross-contamination (i.e. billionaires with too much time on their hands).

Also known as “planetary protection.” Planetary protection / quarantine “reflects both the unknown nature of the space environment and the desire of the scientific community to preserve the pristine nature of celestial bodies until they can be studied in detail.”

There are two types of interplanetary contamination. Forward contamination is the transfer of viable organisms from Earth to another celestial body. Back contamination is the transfer of extraterrestrial organisms, if such exist, back to the Earth's biosphere.
