A floorgy is an event of slight sexual connotation, in which there is a floor, many soft objects, and many people involved. Generally this event involves covering the floor with things such as foam mattresses, topped with blankets and pillows. Then one must add the people, preferrably an even ratio of males to females, or biased based on the host's preferences. The attendees proceed to lay/spoon/fornicate (only if acceptable)in the giant pile of soft goodness.
A floorgy is a great way to enjoy the entertainment of something like a movie, with a large group of people. Then general closeness of people bypasses the possible awkwardness of displays of affection.
Floorgies may not be a good idea in a group of friends that aren't comfortable with eachother, or with homophobic people, so careful discretion when deciding to have a floorgy is required.
Ex 1) Marv, Stephie, Jason and Alyssa had a floorgy while watching 'The Bourne Identity.'
Ex 2) "Hey Mark, we should have floorgies at your house more often, they're super fun!" "Sure Ryan, let's invite many girls and have one right now!" "Super awesome!"
