Okay if that's the case then I'll take it back. Though it sounds like she's still angry at you about something. Either that, or she likes making you crawl. I don't know your relationship so it's too difficult to say.
For me, it depends entirely on the context in which it's used. When the word is directed at another person in anger it can be a funny word. Though when it's used to describe a vagina, I find it quite vulgar and disgusting.
You were being negative about her texting you, so then she became defensive about it. On top of that you then proceeded to push her into saying what she said. So all of this is of your own doing. You seem like a very insecure person and I don't think this woman in question should get the blame for the situation that you're describing. Put simply, you were being an ass.
