Urinating twitch

Something I have always wondered… almost everytime I take a leak I do a little involuntary shake, like a little twitch that runs through my body real quick. I’m sure I am not the only guy who gets this, in fact I recently watched Dumb and Dumber and Jim Carrey does it when he’s emptying himself into the beer bottles in the dogvan. So what is the reason for this?

Search the boards for “pee shiver”. There was a big long thread on it a while back.

Cecil speaks on Piss Shiver (a search of the SDMB archives for that will bring you a lot of discussion as well).
