The Bay County
locals created a nudity
ordinance for their beaches. Obviously they wanted to draw a line between what is and isn't nudity.
After the county sheriff complained that the deputies would have to get rulers and "would have to take measurements on people," the town reworded the laws from what Panama City said, the current law doesn't even bother even trying to define what buttocks are (thank god).
Here is the excerpt of the codified law that made it into The 776 Stupidest Things Ever Said:
"(b) Buttocks: The area at the rear of the human body (sometimes referred to as the glutaeus maximus) which lies between two imaginary lines running parallel to the ground when a person is standing, the first or top of such line being one-half inch below the top of the vertical cleavage of the nates (i.e., the prominence formed by the muscles running from the back of the hip to the back of the leg) and the second or bottom line being one-half inch above the lowest point of the curvature of the fleshy protuberance (sometimes referred to as the gluteal fold), and between two imaginary lines, one on each side of the body (the 'outside lines'), which outside lines are perpendicular to the ground and to the horizontal lines described above and which perpendicular outside lines pass through the outermost point(s) at which each nate meets the outer side of each leg. Notwithstanding the above, buttocks shall not include the leg, the hamstring muscle below the gluteal fold, the tensor fasciae latae muscle or any of the above-described portion of the human body that is between either the left inside perpendicular line and the left outside perpendicular line or the right inside perpendicular line and the right outside perpendicular line. For the purpose of the previous sentence the left inside perpendicular line shall be an imaginary line on the left side of the anus that is perpendicular to the ground and to the horizontal lines described above and that is one-third the distance from the anus to the left outside line, and the right inside perpendicular line shall be an imaginary line on the right side of the anus that is perpendicular to the ground and to the horizontal lines described above and that is one-third of the distance from the anus to the right outside line. (The above description can generally be described as covering one-third of the buttocks centered over the cleavage for the length of the cleavage.) "
Why be so specific, when everybody's got one?
If you're still confused over such a cerebral definition, see ass, butt, or goto Yahoo and type any of those in.
