bodysnarking 

to rudely talk about a persons body or body parts, whether in private or directly at the person;
the snide, often witty comments, about other women's bodies, that have become a part of female conversation;
the practice of dissecting other women's bodies;
to make mean or vicious comments about another persons body

Tabloid culture has made bodysnarking to be a favorite female pastime.
Bodysnarking is one of my favorite things to do while seating on a beach.

bodystacking 

A quasi-sexual practice where fit young men will soap themselves then lay across each other, writhing and often engaging in light frottage.

Jesus... Did you see Simon bodystacking at the four-floors-of-whores? I think some got in his eye.
