Was I wrong here ? Just lost a friend.

Seems like an oversensetive type.
I don't think anybody is in the wrong here, if an oversensetive person let's you know they are, and require that you be a certain person towards them and hold back certain things you might say, that's fine. The problem is not everyone can do that, or bring up the effort to do that for that person 100% of time they're interacting with them, making it very hard for someone to connect with them for a long time.
She let you know she's hard to deal with, you tried your best anyway, didn't work because you don't know how to handle that kind of person, that's okay. Not all friendships are made to last.
Of course, you may have said something mildly insensetive, but the whole relationship you had didn't seem like it would last very long anyhow, so I wouldn't beat yourself up over it.

 

It's kind of hard to say because you're keeping it a little too vauge to make a determination. You just said you joke around with your friend and use words like lame.

I joke around nonstop and I'm only serious when I have to be. My post history indicates that I dont think like a snowflake. I'm constantly messing around with my friends and vice versa. This is a whole world away from being negative, disrespectful and toxic.

I used to hang around friends who were very ignorant and negative. People who down talked each other, exposed each others weakness in front of other people to bolster their own image in front of others, constantly referring to each other as assholes, bitch, fool, niggas, ect. under the guise of having a sense of humor. In hind site these people were negative misguided people who had self esteem issues and a habit of dragging other people down without realizing it. I realized this after i found smarter, better adjusted, productive friends who had a more positive outlook on life and better values. People who have confident and respect for themselves dont associate with these types of people and when I droped all my toxic friends my life and self esteem improved tremendously.

I don't know if this is you because you didnt provide enough detail. She could be a snowflake . Either way I respect her for having enough common sense and respect for herself to distance herself negativity.

 

Well there's that missing bit of context.
I'd say whore is a pretty harsh word for someone dating a lot, also if she already mentioned that name calling doesn't sit well with her.
I know the kind of girl that says "I know I am" to comments like that. The insult, jokingly to you, is something that probably impacts her on a psychological level because she doesn't think very highly of herself, which may also be why she dates a lot, or because she dates a lot, or who knows, that's really just a guess.
I've found that not a lot of women have a sense of humor in that way, not a lot of men either actually. The stuff that actually accurately pins how they feel inside. Men are better at hiding this, probably because they've endured much more banter and jokes.

 

Honestly, I don't think we can guide you on this one. We have only your perspective and some reported speech from her. If she posted a couple of paragraphs it would perhaps highlight an issue that doesn't come over from your description. I am not saying you are misleading us. But it is virtually impossible to see ourselves as others see us. Sorry I cannot help.

 

It's good to move on from toxic people. If that is all you said, it sounds like shes being overly sensitive or may be mad over something else.
