"DTBCN" is often used to reference one that is willing to perform the act of getting butt-ass naked and bake cookies for their partner. The acronym itself implies a sense of female dedication to her male partner surpassing that of normal levels of intimacy in a relationship. If a woman is willing to bake you cookies naked, she's marriage material.
Bob: Dude, not only was she down to bake me cookies, she made me a platter of muffins booty-butt naked.
Joe:I think I just got a boner.
