How Do I Banter Without Being/Sounding Mean?

So, I'm not sure if this is the right place to ask. I'm autistic, not a very social person. I have two friend groups, and I play D&D with them. I tend to banter in a "oh my god, you're so mean, shut the fuck up, (laughter)" kind of way, it's the way I end up most teasing and even able to speak up. But now, one of my friends has said it makes me sound like the bitch, and I'm trying not to be like that. I just don't know how else to banter and joke, I guess.
