^ OK that doesn't make any sense. If OP writes about the double standards, bullying, harassment and sometimes physical attacks that supposedly "provocative" women face, adcoms will think OP is a slut? Some misogynistic medical school that would be.
I think our fear of using the word "slut shaming" (kind of like how people cringe to use the words "rape" and "sex" and "vagina") sort of goes to reinforce the importance of bringing awareness to slut-shaming in today's society. If I were an adcom member I would internally cheer if you used the word, but that's just me, unfortunately 🙁 so I must dejectedly agree with the above posters and advise you to leave the term out. But I think yon can (and should) absolutely talk about the subject! Make sure your PS ultimately shows why you want to be a doctor and what you've done to prove it, but this is definitely an interesting issue and a little-discussed social issue that does have some medical ramifications in some instances, so I think you could turn this into a very powerful PS if you work at it.
