Anybody out there have involuntary vocal uh not sure what to call it maybe a tic?

For a few years now when I become triggered/ really anxious I find myself humming one of two specific phrases. Only those two. It’s like I have no control over this vocal action and I am not even aware that I’m doing it at first. It’s like a quick reaction to my stress at the time; maybe a warning that I need to back off and relax. I think I will just think of it as a friendly warning. But I just wonder if anyone else has similar.
