Couch orgy
A couch orgy is basically the same concept of a grass orgy except without grass and with couches instead!
The idea is to fit as many people on a couch as you can. Usually, everyone is insanely uncomfortable and sweaty (especially if Christ is on you...wow that sounded sick). It gets gross. But it is still a lot of fun!
Corgies are discouraged by RAs due to the potential for damage to furniture which was not designed to hold such a large number of people. There has been at least one instance where weight overload has led to couch damage (and subsequent couch replacement); the money to buy F&M a new couch was taken out of the CTY scholarship fund.
The most on record (at least for LAN 06.2) is 20 people on one three-person couch, one two-person couch, and two dining chairs.
Also, a couch orgy can be called a corgy or chorgy to shorten it up, but it doesn't sound nearly as fun as a couch orgy does.
