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.

A person who is both dumb and an ass at the same time. Contrast with "dumbass," which is a conjugate of the terms, thereby creating a new class of person. However, "dumb ass" confers a meaning by which a person is both embarassing to the human race and of below average intelligence.
