A party, with one stool, with three or more legs (eg, a bar stool) where any number of people are invited to either watch or participate in the 'stool dance' where the participants move down and up on the stool legs (sometimes while clapping) until 'completion' (using the anus or vagina).

After 'completion' it is customary to move on to the next leg, or give someone else a go, but often, all but 4 (or 3) people only go to watch.
Last night, john went to the upside stool party, he said there were over a hundred people there, but only 4 came.

I've been invited to an upside down stool party, I'd better lube up!
