What is your version on what a slut means?

I've been seeing a lot of females on my Facebook comment on this video of a girl being shamed for her outfit .. A man is screaming at her calling her a slut and saying that is why woman get raped. I shared the video because at the end a random woman gets sick of hearing him and bashes him over the head with a beer bottle and I said I would be the woman to do that. I would be that girl to smash him in the head. He was in her face screaming.

Well, so many girls commented on it saying "if you don't want to be called a slut, don't dress like it" I'm in shock. I don't even think that is a thing. A slut. Most people say its someone who sleeps around where is think sleeping around is your choice and it's your body and sex is good if its SAFE AND CONSENSUAL. I don't care IF your number is in the 1000s . if you where safe I think its liberating. If you aren't sleeping with someone who is taken, who cares? And how the shit does someone dress slutty.
