The art of suprising your partner in a doggystyle position and adding a "bonus" Wich is puttin your 2 thumbs togheter and fingers up to form the shape of THE falcon, then inserting the head "Both thumbs" in your partner's anus while screaming like a flacon. To make it dirty you do it without lubrification. And to make it a Dirty fierce falcon, while you have both thumbs in your partner's anus, you spread your thumbs each side.
