“Secret” is tongue in cheek.

We know people flash the white power hand sign when having their picture taken, as if it isn’t a racist dog whistle.

The Bloods have a hand sign. I’m impressed that one can spell the entire word with one’s hands.

Jeep drivers have a cutesy hand wave that signals a common identity with other Jeep drivers.

AFAIK there’s no hand sign that espouses the Eat The Rich sentiment. There’s an opportunity to create something new where one doesn’t yet exist.

If “Eat the Rich” produced a secret hand gesture, what would/should it look like?

I understand the argument of “This doesn’t help; instead write to your congressman or volunteer to burp newborns.” I get that, but this is independent of that.

This truly belongs in AskLemmy but their (justified) temporary ban on US politics seems to discourage this question.
