VERB - An upstairs is when you remove the lid from the back of a toilet tank, and proceed to either piss and/or take a dump (the idea method) right into the clean water and put the lid back on. If done right, the turd will float around in the tank and foul water will come out when the toilet is flushed, and also in case of an emergency, the normally potable water in the tank cannot be consumed.
