This is not specifically about Darija, but about gestures used or understood in Morocco. I though about when I saw this :na: fella. Also the thumbsup one seems quite widely understood around the world. But for example the way people (well, no, not people in general but men) hitch-hiked in Morocco was completely new to me, and it took a while to figure out - I thought they were pointing at something to warn us about it! (I don’t know, this may be common in other parts of the world as well, I’m just unaware of it. The hitch-hiking technique I’m familiar with is pointing your thumb along the road :))
Are there more specifically Moroccan or North African gestures you’re aware of?
