Basic Trope: Person A heaps abuse on Person B, but when Person C tries the same thing on Person B, Person A leaps to their defense. * Straight: Katie is constantly calling Bob lazy and fat, but when Gary calls Bob fat? Katie springs up, saying, "Hey! Only I can call Bob that!" * Exaggerated: Katie never says a single good thing about Bob. Ever. But when someone remarks, fairly neutrally, "You're awfully tall..." Katie springs up, saying, "Nobody is allowed to talk about my Bobby-wobbykins that way but me!" And then gives said person a Megaton Punch. * Justified: Katie knows Bob well, and knows he'd rather hear the tough truth than a white lie. But while Katie does it out of genuine concern, Gary is just trying to be insulting. * Inverted: Everyone else insults Bob mercilessly
