I was at a meeting recently and noticed that one of my colleagues moves her head a great deal in conversation. She said, "And we thought—" and then she shook her head from side to side, like someone refusing a hit of weed, "—that there wouldn't be," etc. It was rather distracting and caused me to wonder why she was performing this bit of théâtre de gérance, so to speak.

I can't for the life of me remember what point she was making. And maybe that's the purpose: "Don't pay attention to what I'm saying because I'm not really saying anything, just watch me waggle my head in this display of competence." Is that possible?

I drew an interesting picture during the rest of the meeting.
