Hand gestures are the reason Arab conversations resemble a heated wrestling match almost always. Truth be told, conversing with another human just doesn't feel real if hand usage isn't present.
One Twitter user recently posted a photo of one gesture dear to Arabs, accompanied with "Caption This" in his tweet. Lots of Italians, some French, and a few Asians pitched in, but it was the Arab comments we were anticipating.
In the history of gestures, nothing has ever said so much and marked us so deeply as much as this folded one. Arab Twitter users definitely know what we're talking about.
