I think of head-shaking and eye-rolling when you express an opinion or ask for something you need. That's clearly designed to make you second-guess yourself and think twice about speaking up next time.

Definitely on point about the angry glares. My ex-husband also used to include hand gestures with that. Either he'd flip the bird, or there's one where he would place his hand on the opposite forearm and then raise his closed fist. I believe it's a common gesture in parts of Europe (we're Americans, though) and it translates, "up yours."

General shaking a fist is also designed to intimidate. Also things like punching walls or slamming fists down on tables. The message in that is, "you're next."

And then there's the leaning forward on the edge of their seats, as if at any moment they're ready to leap up and spring at you.

Let's not forget that satisfied "yeah, I got her; target hit" smirk when they say something that hurts you.

Be prepared for their abject denial of ALL of this. Call them on it, and they'll claim they never made any gesture or looked at you any kind of way. It's all your imagination. You must be paranoid or something.
