Top definition
An excellent prank whereby you pee on a plate and then freeze it. Once frozen, it can be thrown like a frisbee or better yet, slid under a door. The victim wakes up to find a puddle of piss on their floor that they can't possibly explain.
That bitch thought she could talk trash about me, so last night I slid her a piss disk.
