fanny beard
You will require a girl with a hairy bush. Flip her upside down spread her legs, go behind her and rest your chin on her fanny. A mirror is best at this point to check out your fanny beard. You can use ladies with differing colour hair to get your desired look.
Flipped my bird upside down last night and took a fanny beard selfie. My birds sporting an 80s bush at the moment.
