It’s kinda funny because the insult itself is actually an appeal to their male insecurity because they can’t handle the idea of a woman doing anything with other guys or even just being attracted to them, hence their strong negative association with those words.

Like not really “haha” funny but “using that insult says more about you than it does the target of the insult” funny.

Younger me was confused about “slut” being an insult because “slut” sounds way more fun than “prude”.
