messy one

"having" a shit, that creates a MESS in the 'tocks, requiring MANY MINUTES of sanitation (cleaning) work and MILES of "terlit" paper! taking MUCH MORE time to 'clean' than a "wipeless" shit !! the quickest , easiest (and most sensible) fixes are WATER !!
(if NOT on the f**kng JOB!) via shower or bidet (preferred , if outside uncivilized 'merca !!)

if one has the misfortune of walking the rest of the day, too much "residue" has the effect of "whistling" for I.A. (irritated asshole) the 'tocks serving as a 'grinder' , rubbing it in the skin!

always have envied the way it just drops off a dog's "buttle" ! you CAN'T "wipe" a 'nugget' !! ("dingleberry" ? )

let's GO doug !! -going to be a while ! , i just 'blew' a messy one !!
i was late for work , due to "having" a messy one !
i gave 'birth' at work, but it was a messy one !!
