A period in which an adult man disguises himself as a woman in order to secretly spend time with his children.
Not to be confused with a Tootsie weekend in which a man assumes a female identity for a short period to determine whether or not he would enjoy being a woman.

The Doubtfire is when a man busts a nut in a women’s ass, then the man lies down and allows the women to fart in his face while yelling “hello!”.
Definition derived from the scene in “Mrs. Doubtfire” when Robin Williams smashes his face into a frosted cake to cover his male face.
I let my side bitch give me a Doubtfire last night.
