A dick hickey...a hickey on your dick.

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.

An article of clothing originating from the era of thoracic dignity. Comprised of a finely pruned turtleneck vaguely resembling a miniature poncho, the dickey served no purpose other than to warm the neck and cover the cleavage produced by a significant bust. Often referred to as a 'turtleneck illusion', the dickey continues to become an increasingly obsolete garment as the age of the breast falls upon us all.
