Supposing that she did say “I’m gonna wipe my hands dry on my penis” in order to provide a menacing reminder of the existence of her genitalia… How effective of a threat is that, really?

Like, try imagining someone genuinely trying to dry their hands using their dick. Idk about you, but my mental word cloud for that concept reads something like “weak”, “pathetic”, “lost”, “incompetent”. Not a very threatening concept.
