The Wingman Technique usually involves (and is best preformed with only one) friend accompanying another to a club or other social setting. If one friend finds a hot girl who is accompanied by an ugly friend (i.e. grenade), it is the sworn job and duty of the accompanying friend (the wingman) to occupy the ugly girl so his friend can get action with the hot girl. The revered duty and purpose of a wingman is to streamline the night for his friend as much as possible, tackling any obstacles and cockblocks.

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.
