Sack Beard 

Full-to-Medium length hair left on the scrotum after trimming or shaving has clearly been done to the major part of the pubic area.

Roxanne: So me and Ted finally did it.
Sheila: Does he "shave"?
Roxanne: Yeah. Well, sort of. He still had a Sack Beard.

A luscious growth of pubes extending downwards from the scrotum.

Dude, my sackbeard is so lush I have to use a hair-dryer after I shower.
