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.
