The sex couch is a piece of furniture (doesnt have to be a couch really) located in the prop room connected to a drama classroom. When feeling the need to relieve stress with someone of interest usually drama kids will ask to go look for things in the prop room... While in the prop room they do not actually search for anything but take a spin on the sex couch. Everyone in drama ends up finding out about the sex couch and half of everybody uses it at least once for sexual purposes. Yes teachers know abot the sex couch but they will never get rid of it. It will always stay in there. If using the sex couch, it is advised to use responsibly. And remember before you sit on the sex couch... What happens on the sex couch, STAYS ON THE SEX COUCH!!!

EX: Dude! Did you hear what those two did on the sex couch??... Man, don't sit on that for a while!!

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.
