The portion of the porcelain toilet rim that is exposed by a u- shaped toilet seat.

In public places (or dirty homes with a u-shaped toilet seat) the area of the toilet rim that dried up pee, and lone pubic hair escapees gather.
Every time I take a poop in public, and I wipe, my arm hits the piss rim!!!

Or

Last night, I was so drunk. I threw up so hard I held onto the piss rim for dear life!!!
