Living together with several different sex/romantic partners. To have multiple girlfriends or wives, all of whom know about each other and live in the same house. Polygamy.

Originated thousands of years ago as a means of producing a large number of offspring, and as a status symbol, to show off how many women and children a man could afford to provide for, and to display virility. Now banned in most countries, but was once common practice, even in early Christendom: Charlamagne had multiple wives.

The word was recently popularized by one Ricky Lackey, a convicted thief who, when asked by the judge at his trial how many children he had, replied: "None now, but I have six on the way." When the judge asked if he was marrying a woman who had six children, he replied "No, I be concubining." Meaning, of course, that he had 6 girlfriends, all of whom were pregnant.

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.
