A sexual act that involves the female lying on her front with her head lifted up facing forwards and her legs lifted towards her head. A tray of tortilla chips is then carefully balanced up on them. A male then begins to receive oral sex from the female, whilst having a tasty snack of his own.

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.
