look up any word, like donkey punch:
 
1.
When four guys go to the bathroom and use the ONLY four stalls at the same time. They empty their systems, wipe and flush all at the same time. The force from the 4 toilets flushing at the same time, leaves one toilet unflushed and this toilet must be left unflushed. During the Four-way-quad-shit, the four individuals may discuss different issues such as whether or not it is possible to wipe using only two squares.

However this process is quite secretive to the four individuals and to prevent from scaring people who are unaware of it, In public it must be referred to as the quad.
I had to go pretty bad, so I asked my buddys if they wanted to pull a Four-way-quad-shit.
