Well, pisscat/elkassasin,
I finally looked it up.
We may all unite together, get a vote, and change the MM definition of Pisscutter. Crazier things have happened, look who the hell we elected as President TWICE!
Here is the official Definition of PissCutter:
What say ye all, shall we vote and change the MM definition also?
Pisscutter
Piss - as in "a constant stream of urine"
Cutter - as in "a device that can physically bisect an object"
When you put these words together, you get: "a device that can physically bisect a constant stream of urine" - a "pisscutter" so to speak.
This word was first uttered in Schreiber, Ontario and is used to describe the sheer awesomeness of something. It can be an idea, an object, a time in history, etc...to refer to a subject as being (a) pisscutter is to say that it is so awesome that it can actually perform the impossible act of cutting a stream of piss.
