Today, during our meeting, I had a coworker hide his face with a paper and quietly made some kind of joke about me to the person next to him while I was talking and they had a laugh. He did it twice. I'm not saying anything stupid, the guy just doesn't like me. I don't care for drama but I don't like that he's disrespecting me in front of the others. I'm in my 20s and he's in his 50s, by the way.

I know the solution on TRP is that I should remove myself from the situation. But in this case, I can't not show up and speak at the meetings. I know the other option is to find another job and that is something I'm planning to do in a few months after I finish a few projects to build up my resume. So I'm stuck here for now.

But until then, if this happens again, what is a witty remark to say during a situation like this? I still plan on talking to him afterwords and telling him that I expect more professionalism from him.

By the way, for my job, I need his buy-in, so I'd like to not completely destroy our work relationship.
