(noun), Poo Of Unusual Size.
Based on the terminology used in the movie The Princess Bride, in reference to the R.O.U.S.'s (Rodents Of Unusual Size) found in the Fire Swamp.
This is an extremely
large poo, at least a portion of which exhibits exceptional girth. This type of poo usually exits very slowly and after a stressful episode of exhaustive straining, suddenly drops into the
toilet. This is the correct and technical term to use, although this type of
doody is often mislabeled as "doodying out a coke can," "crapping out a watermelon," or in general, when someone claimed they shat (past tense) out a friggin' <insert
large object
name here>.
Note that during a P.O.U.S., you may experience intermittent symptoms of
M.W.P., (Machete Wielding Poo).
