a homosexual maneuver, when guy A is standing up (with a boner of course) and guy B puts his head in between guy A's legs sucking his dick, but guy B's dick is also in guy A's ass. usually guy B has to be a midget or more politically correct a "little person" for this maneuver to occur. commonly referred to as the "human diaper."

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.
