<human>: Condense the text into a few key points

Hi RA, I'm back with another weird ass post...

I wanted to get your opinions on name calling, and what is considered 'playful' vs what is disrespectful. My GF (27F) and I (27M) recently had a very immature argument revolving around name calling. I understand that it's all in good fun to take jabs and jokes in a relationship, so maybe I am being over sensitive.

So here goes, I called her and she picked up the phone and said 'Hi squirt'. I was a little taken aback by it because she has also called one of our mutual friends (whom we both find to be kind of naive and annoying at times) 'squirt'. It wasn't really a big deal so I just kinda laughed it off and continued the conversation, but soon, she joked around more and called me 'kiddo' (which she sometimes calls her little brother). At this point I was just kinda annoyed about it, and after a minute or so, she wanted to play games online with me and insisted that we talk on instant messenger instead of phone. I hadn't really talked to her much that day until this point, but I decided to just go ahead and hang up and sign on so we could play.

During the game, she is beating me so of course she is talking some crap, which was okay until she called me 'twat'. When I saw this, I got really annoyed and shortly after I confronted her about it. We got into an argument and she said that I am too sensitive and that its a turn off to her when all she was trying to do is be playful. All i wanted from her was an apology, and when she gave me one out of obligation, the argument was basically over.

So RA, am I being oversensitive? I normally really don't care if I get called names in all honesty, but I just feel that some of the things she says (especially in context) are kind of disrespectful to me - her boyfriend. Am I right to think so, or can you slap some sense into me?
