Occurs when movement of yourself or a certain objects causes a sound that mimics a fart. This usually involves chairs (or bar stools) or Velcro. The corresponding noise is then misinterpreted as a fart, and results in a awkward moment of either silence or unnecessary explanation.

Sometime only the maker of the noise realizes that they have caused a misfart and proceeds to explain themselves, thereby causing even more awkwardness.

Occasionally, especially when alcohol is involved, the misfart is actually a real fart, but the suspect believes they can mask it as a misfart.

May or may not be closely followed by a courtesy fart.

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.
