Is all this happening on work time or in your after work hang out time ? I would ignore him from now on . I would not get emotional over him if he does this again . If you can ' t ignore it , then you must operate on a higher level , where you are in control and everyone can see it he is an ant to you that you watch scurry about in a predictable manner . I had a bully once that had a classic napoleon complex below 5 ' 6 and aggressive toward the tall skinny guy I was at that time . After he gave me his usual pointed quip , I said stoned faced to the group Jeremy seems to like to pick out one person and say these sorts of things because it makes him feel better about himself . His face went instant scarlet red and he never did it again . So , if you have to confront him verbally , make it so that the group recognizes what is obviously transpiring . Pointing out the absurd obvious is a great tool for comedy and this type of social warfare . Edit If this is happening after work hours not paid to be in the group , then you can leave the group or reform it without him in it .
