A woman who thinks that all things related to her wedding MUST be controlled by her or by her direct designate (see bridesmaidzilla) because she is under the premise that the wedding is "her" day. In planning weddings, her attitude ranges from very difficult to impossible. Can be nasty, snippy, rude, belligerent, caustic, aggressive and demeaning when others get involved in planning "her" day.
She didn't understand why her friend couldn't sing her favorite song at the wedding, and made life miserable for the church music director! What a bridezilla!
