look up any word, like the eiffel tower:
When a man dresses up as a woman, but is not really a transvestite. The reference is from the movie "Mrs. Doubtfire" in which Robin Wiliams dressed up as a woman to get a job working as a nanny for his own children.
That pervert Bobby has been doubtfiring his way into the women's locker room at the gym...

the act of a man dressing up as a woman in order to be closer to those whom he loves most
Did you see that linebacker-sized nanny go blazing across the restaurant? I think she's actually a dude doubtfiring to get his kids back in his life.
