A code name for a really shitty roommate who never cleans up after themselves or takes any responsibility for their actions. Goes long periods of time without showering or washing any of the clothes they put on. Tends to act very promiscuous sleeping with older men and possibly drug dealers all while having a boyfriend. Also a good chance of scabies infestation due to the previously mentioned promiscuity.

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.
