(kay-chan)

A representation of a diseased phallus.

Coined in the 17th century by a Chinese philosopher Wang-Kock, the Kchan was an illustrious example of what a penis shouldn't be. It was the metaphorical symbol used to indirectly describe a lack of manhood, a huge degree of promiscuity, and an unfortunate creation of evolution gone wrong.

It is now used to describe someone or something who most likely has a diseased phallus.

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.
