A term used in beer pong that replaces a team mate that went MIA for usually just a throw. The replacement can be anyone near the table choosen by the single player. This term is put in effect if the missing team mate taken a piss, droppin a deuce, or just unavalible at the time of his throw. This keeps the game flowing.

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.
