The occurance of splashback during a number 2 that is so accurate, it returns straight back to the point of origin inside the anus. Can be greated with a sly smile of self satisfaction.
A phenomenon which defies all known physical laws when, regardless of size, density, height, force and slope, a dump fires bogwater skywards and strikes the victim directly in the butthole or genitals.
Generally occurs only after you've already pissed in it.
Oh man, splashback! What the hell? That crap was tiny...
when the guy blows a load in the toilet and forgets to flush or doesn't flush, then the woman goes to the bathroom, drops a deuce and the splash from the turd splashes up with the load...and boom there you have a baby 9 months later...."I shall call him lil shit"
