Words have different meanings for different people. Some offend, some seem pretentious, some are just silly. The words I'm thinking of, are just simple words, that bug us, or make us a bit uncomfortable. Like "moist", I guess there is some science behind it. I haven't read it yet.
Mine is "hump", used in sexual context. I believe it's because it reminds me of elementary school. I have heard it used by adults, that is when my face scrunches up, and I think "ew"

"Moist" is horrible. It actually activates my gag relfex.
LIKE, which has been used for years now, especially by teenagers.
Panties. I HATE that word. Just call it underwear.
It is easier to say take your panties than take your underwear off
