A guy/girl you meet at a rave that acts like a S/O until the end of the night and is never to be seen again after the rave is over. Job description includes, but is not limited to: disappearing together for the entire rave, hardcore grinding, repelling lone ravers in your vicinity, and meeting other rave bae couples. Rave baes are usually harmless and plur-friendly, but an encounter with the occasional crazy rave bae is not uncommon.

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.
