This phenomenon occurs when one is defecating in an unclean and/or unsafe environment, and does not wish to make physical contact with the toilet seat. As a result, the person performs the squat maneuver. This accomplishes two things: first, the point of exit for the stool is at a considerably higher elevation, resulting in a high entry velocity. Second, as a result of the
pivot point being above the feet, the point of exit is further forward in relation to the bowl. This point of release may be so far forward such that there is no (or shallow) water directly above the asshole. If the consistency of the crap is just right, it will land and stick, remaining in an upright position. If the center of mass is directly above the area
spanned by the base, the log will be in metastable static
equilibrium, and will not fall down. This is commonly known as
the lighthouse effect.
Note: the lighthouse is said to have
weathered the storm if it remains even after the ensuing flush, such that there is no toilet paper or urine detracting from the natural beauty of the phenomenon.
-Dude, I just left a lighthouse in that
bathroom!!
