An vagina that hasn't been shaved ever and has a huge amount of hair. Its like a normal beard if you don'tshave it for about a year. Except on a girls vagina.
Guy 1: Dude I saw Brittany naked.
Guy 2: Does she have a vagina beard?
Guy 1: Yeah. Yeah she does.
Guy 2: Ew
when female reproductive organs contain so much hair that if you cut it all off you could glue it to a viking's face and it would pass as a normal beard.
