Also referred to as "G-No-Wipe-Poopie"
A ghost no wipe poopie refers to a situation where while engaging in defecation, one feels a dropping exit the anus and hears the incurring splash. However, upon wiping the sphincter, no remnants are visible upon the toilet paper (no wipe poopie). In addition, the droppings appear to be absent from the toilet (ghost poopie).
The result can be frantic forced recollection of whether or not the poopie actually existed. This could possibly extend into more serious psychosomatic disorders like schizophrenia, bipolar disorder, obsessive compulsive disorder, eating disorders, and, of course, defecation disorders.
