A celebration of some sort, that is not large enough to be a party, but too big to be a gathering. The definition is quite loose though, and if you do use it, it is more than likely that you will just spend hours arguing weather or not the celebration actually is a partathering or not.

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.

One of the best events that can be thrown by Sixth Form Students, especially those Middle-Class students who live in relatively quiet suburbs with old neighbours.

Not large enough to be a party (40+), but not small enough to be called a gathering (-10), a partathering usually has the following things:

*cool people
*excessive amounts of alcohol
*binge drinking
*cool host(s)
*drinking games - mainly King Cup and Spin the Bottle
*pulling but not often clunge fun
*someone going "GUYS. KEEP IT DOWN. THIS ISNT A PARTY"

Half way between a party and a gathering. If you have say 20 or so people its more than a gathering and less than a party, its a partathering.
