The first word that came to mind was "moist." It makes me think of moist towelettes, and usually whenever I see it, it's being used to describe how turned on a girl is, and it just doesn't fit to me
Pussy. I cannot stand that word, and a lot of the music I listen to uses it, so every time I hear it, I just cringe inside.
Words used in smut to describe parts of human anatomy that sound like they were ripped from a textbook (prostate, penis, vagina, testicles, anus, clitoris, etc). They tend to sort of stick out like a sore thumb to me whenever I'm reading something.
