Scottish dialect form of "pissing". Basically means "urinating".
by Rabsputin September 3, 2011
To piss, but in a way that silences the splashing or tinkling sound.

Commonly achieved by aiming the piss at the inside of the toilet bowl or by padding the bottom with toilet paper in order to muffle the sound.

Often done when you don't want to draw attention to your piss.
"I had to use the public toilet yesterday but I was scared I'd make too much noise so I had to resort to pishhing"
