A phrase coined by Teresa Strasser of the Adam Carolla Show on Free FM which refers to social outings that would normally be considered dates, but where one of the two people involved seems completely oblivious to the concept of dating. This is generally characterized by a lack of interest in conversation or flirting, an aimless absence of direction or goals for the evening, and possibly an uncomfortable revelation that the event was never intended to be date. This can be blamed on the modern tendency for self-absorption and a narcissistic belief that you shouldn't have to put forth any effort to be interesting or even pleasant.

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.
