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.

NFC, an acronym for "No Fat Chicks", can be used in multiple ways. It can be applied to simply represent a woman with large body mass - such as "did you see that NFC", a label - such as "NFC Emily", or as a literal translation of its meaning; "Come check to my party - NFC!"

While derogatory, its generally considered good taste not to tell NFC's what the acronym means. If confronted as to the meaning by a whale-like female, come up with a definition; "No fucking clue", "Nice facial caricatures", etc. It's imperative you dont let an NFC know what the definition is - lest you be sat on by a large mass of carbon, water, and ugly.
