The
result from the tendancy of
liquid traveling at a high enough rate of
speed to
rebound off of a hard, non-absorbant surface (like the back of a
urinal) and wet the person standing at the point of origination.
Specifically, this is when, while
taking a piss, some of the urine splashes back onto your pant leg. Especially common if you are, like me, taller than the average person. A combination of low hanging urinal and a
package about six inches higher than where is
ergonomically average just
exacerbates the problem.
