<human>: I'm in a group of about 12 people. I'm a single woman, most of the rest of the group is made of couples. All the men "pick on me" or whatever you call it. I'm the one they all joke about and with, very rarely anyone else including the other 2 single women are involved in the sarcastic banter. Is that just me as one of the guys?   
  
I like to dish it right back at them all. I think sarcasm is funny but it's also a fine line to do it correctly. I am close with all their wives, in fact, I'm only friends with the husbands because of my friendship with their wives.  
  
We recently got a new single guy in the group, and he seems to give me a LOT of extra shit. I'm wondering if he's just trying to bond with the rest of the group by doing that or if he's trying to assert something? His "jokes" are a bit darker or pointed than the rest and he eyeballs me when he says them. He doesn't sit by me and seems maybe uncomfortable around me? Sometimes it gets a bit old and with this new guy they seem a bit hurtful. Maybe I'm just being sensitive, but I usually don't get ruffled by joking around. We're actually really similar and in some situations he and I laugh and get along really well. It's when we all go out and everyone gets dressed up and the mood is different it seems.

Can you give me the gist of the text in a nutshell?
<bot>: New guy in the group seems to aggressively be sarcastic with me and I can't figure out his motives or what to do.
