For additional quotations, see bitch slap.
Things are a little better when Doris ends up spending her “honeymoon” night in the tub with the sprinklers going off, and there is a genuinely amusing catfight between Ethel and Marcia in which Doris actually—there’s no other phrase for it—bitch slaps Marcia; it’s funny because Marcia is a loser, a whiny, imperious daddy’s girl, and worth neither Ethel’s time nor Winthrop’s attention.
Top this all off with an occasional bitch slap or ass-chewing and you’ve got yourself a real recipe for breaking even the strongest spirit.
