Slag lots of times but this was the first.
I was 13 he was late teens.
My crime: I walked past him and did not look at him when he said "alright darling"
Whore
Countless times but the one that sticks in my memory.
Aged 16 he was in his 30s with his mates outside a pub.
My crime: i said no thank you when he asked me for a fuck.
Just a tart
Aged around 19. Him same age.
My crime: I declined his offer of a drink in front of his mates so i was labelled just a tart who was out for free drinks. 
Hysterical bitch
Aged 22. Him about same age.
My crime: I told him to fuck off after he repeatedly grabbed my arse while I was waiting at the bar.
prozzy
Aged 22. Him much older.
My crime: wearing a short skirt.
Quite a few years of all the above comments then:
Ugly bitch
Aged 39. Him mid 30s.
My crime: To say no he could not sit on my knee in the pub I was drinking in.
Fat slag
Me aged 40. Him late 20s.
My crime: Telling him to fuck off after he pushed me out of the way in a very long taxi que I had been stood in for 20 mins and I was next in line.
The last one ^^ was last Friday evening.
In all my years I have never called men vile names like I have recieved.
One because I am not rude and vile but more importantly because I fear they would attack me if I spoke to them the same way.
The younger me used to put up with it keep my head down and move out of their way.
The older me fights back a bit but I am still scared they will hit me if I do.
Feel free to list your own.
