Basic Trope: The Distressed Damsel is offended that the bad guy(s) didn't want to molest her. Nearly always played for laughs.
Straight: Dirk Dastardly's men burst into Helpless Holly's room. They do not rape her. "What!" she cries, "am I not pretty enough?"
Exaggerated: "What? I'm totally helpless and Bob isn't here to save me. Are you absolutely sure you don't want to ravish me? No? Hmm... Oh dear, I just tore my dress open. Whatever will I do? These nasty people should ravish me for sure now... *beat* Oh, for crying out loud! Do me!... *sniff* *crying* DON'T LOOK AT ME!"
Holly is relieved that Dirk's men didn't ravish her but feels a slight, embarrassing twinge of offense at the idea that they didn't find her appealing enough.
Ivy is annoyed that the men on the street don't oogle here, though she would have set her guards on them if any of them had even moved toward her.
Justified: Holly has taken a vow of chastity, so the only way she can ever have sex without losing her honour is if she is to be forced. When Dirk's troops raid the palace, she is dismayed to find that they believe that Rape Is a Special Kind of Evil.
"No," said Holly, "I'm not being ravished by you." Dirk Dastardly gave a groan of dismay. "I was looking forward to that! Am I really that ugly?"
"Thank heavens, I was afraid for a moment that you'd respect me."
Invoked: Dirk drip-feeds Holly stories via her servants that it's wonderful to be ravished. He then organises a raid on the palace and goes on to Exploit (q.v.) this trope.
Exploited: Dirk orders his men to leave Holly untouched, in order to make her feel insecure about her beauty.
Waiting for Dirk's men to burst into the room, Holly's sister explains in no uncertain terms that being ‘ravished’, as Holly dreamily calls it, is not nice, not a compliment, and not to be invited.
Alternatively, Holly's sister tells her that if someone rapes you it's probably because they want to feel powerful and see you as vulnerable and therefore an easy target, not because they actually think you're pretty.
Discussed: "We'll have rescued Holly by the end of the day, and I don't think she's in much danger of being ravished...matter of fact, that might offend her a bit!"
Conversed: "You would think that Helpless Holly – what a name! – wouldn't really mind not being molested. Silly book, this."
Holly has a lighthearted view of sex. After she asks, Dirk's men do rape her, and she quickly finds out that encouraging them wasn't a good idea.
Alternatively, the reason Holly wasn't relieved was because she thought she'd be able to fight them off anyways, so it won't make much of a difference, only to realize she was wrong the hard way.
Holly has self-esteem issues & doesn't realize that for some rapists, it's more about domination and vulnerability than actual attractiveness. When they do rape her, she wonders why she doesn't feel pretty.
Or Dirk's men have different standards of beauty than her and find what she'd find ugly attractive and vice-versa. So in a way, she should be flattered they don't find her attractive.
Holly sees sex as a tool for manipulation and a way to gain power. She wants to distract Dirk's men with her body until the police arrive, and is dismayed when she finds it doesn't work.
Played For Laughs:
Holly expresses disappointment when the men don't rape her at first. Cue Black Comedy Rape.
