Buttocks décolletage refers to a fashion in which the person deliberately wears her jeans or other clothing short or low enough to expose the upper part of the nether cheeks and crack. This can occasionally be done either by males or females; and usually the person provides this exposure deliberately. However, some plumbers may not be so aware. The general consensus of buttocks décolletage is to tolerate it if done by plumbers, as this is should be considered an occupational perequisite.
Usage example: "The dress Wendy tried on allowed too much buttocks décolletage, even for the Gulf Coast beach hangouts."
On the other hand, there is a Biblical argument in favor of buttocks décolletage: "Turn the other cheek." I'm sure that this would be persuasive to preachers in the western part of North Carolina where such sights are not unheard of.
However, a few communities have passed ordinances against young men wearing their pants so low as to display their undies. The thrust of these ordinances seems to be more esthetically- rather than modesty-driven, as the undershorts cover the nether parts in question. I wonder if this is a peculiar form of sex discrimination directed towards males.
