It's pointless and should be deleted, as it is basically just a synonym of pubic_hair. I assume the original intent was for images featuring people drawn with unusually large amounts of pubic hair, but very few posts satisfy even that description. Posts like post #481496 certainly don't. "Unusually large" is painfully subjective anyway.
Maybe keep it around for posts like post #4393, for people with lots of body hair.
