A self-deprecating term used to describe a category of media that is defined by a combination of shared nostalgia and embarrassment. This word is typically used to describe fads, songs or movies that a person wouldn't want the general public to know that they once enjoyed, but is okay laughing about with friends.

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.
