a.k.a. GSR

noun.

This is when more often a male shaves his trail, bush, etc, and wears his pants, trunks slung so low that it's clear that he no longer has hair where he ordinarily would.

The GSR is most often spotted at the beach on young, body conscious males or in night clubs on males that you know come with a side of chlamydia.
