An unholy merging of hip-hop low crotch baggy jeans and hipster skinny jeans. The resulting fashion nightmare can range anywhere from making a chick look like she has a dick to making her look like she has a huge gunt or even a birth-pouch. Also looks like pants on backwards.

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.
