Jul 15 Word of the Day
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.
Billionaires are having a dick swinging space race while the earth experiences record breaking heatwaves that cause sea creatures to literally cook inside their shells. We need planetary quarantine.

Something interesting, but for which the content and/or manner has negative or scandalous connotations.

The word was first birthed as a result of the popular TV show "Who's the Boss" where Tony Danza's character exclaims "That's interesting!". As a result of Danza's notoriously criticized articulation, the 's' merged with "interesting" to form the word "Sinteresting".

Today the word is chiefly used online. It has been applied to the gossip surrounding the recent Kanye West fiasco, and to describe uniquely brutal displays of skill in the online gaming scene.
Example:
Gossip is a form of sinteresting information.

Use 1:
Rodrigo: "I heard Santiago was having an affair"
Gabriela: "Sinteresting! Tell me more!"

Use 2:
Rodrigo: "Did you see that combo video!? It's so sinteresting!"
