The delicate skin located between the vagina and the anus, sometimes used by men (and some women), as a breather during prolong and intensive beaver eating session. It's vital to add that the majority of women would prefer a post-shaved chin. Some women can tolerate a beard stating that it excites the surface nerves, and can cause moderate orgasmic quakes.

SURGEON GENERAL'S WARNING: There have been numerous complaints that a 2 to 3 day growth of stubble can have the same effect as 100 grain sandpaper on this delicate area.
Herbie was new to this, but he was getting the hang of it. Now, 25 minutes later, he sensed trouble when his lower lip and jaw started going numb. Plus his lungs were crying for fresh air. "Dammit!", he thought. He unknowingly dragged his stubbled-chin roughly onto Sally's chin rest, removing a couple of layers of skin in the process and mumbled weakly, "Time-out."
