A handle (pseudonym) that was used on dial-up BBSs in the late-1980s until approx. the turn of the century. Used on internet BBSs (forums or even fora if you want to be anal about it!) even to this day {early-2013}.
Can also be used to describe a potato that tastes like piss.

That nasty collection of plastic balls at the playgrounds of fast food restaurants across this great country of ours. Those balls aren't wet because it rained, it's because some kid peed in the play structure.
Child: “Mom, can I go play? I’m done with my happy meal.”
Mom: “Yes, just be sure to stay out of the urine balls.”
The requisite one urinal minimum you put between you and any other men who may be pissing at a row of urinals. It's a courtesy thing, and it's about proximity more than line of sight: shame shields don't obviate the need for a buffer urinal.
Of course, when you're in a situation where the buffer is impossible because there are more men than there are urinals (sporting events, concerts, etc.), the buffer urinal no longer applies.
I took my place in the row, making sure to leave a buffer urinal between me and the blonde.
When the mens room at your office building has not been cleaned for an amount of time that allows the rim of the urinal to collect pubic hair. The collection then appears like a mustache on the rim.
I almost puked when I had to use the restroom and the urinal mustache tickled my hand.
