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 code word for an amount of marijuana. Originally 5.6 grams of marijuana or one 5th of an ounce. Often confused due to the term "dime bag" code for a $10 bag, the term "nickel bag" was never measured on that same scale. Many avid smokers use this to identify posers and noobs. Where a dime (ten cent piece) refers to ten dollars worth, a nickel (five cent piece) refers to 1/5th of an ounce. A nickel is in fact worth more than a dime when referring to an amount of marijuana.
