The Handkerchief code , used in gay culture to non-verbally tell what sexual practices you like

In France, high-schoolers are launching a revolution, new generation rocks!!

In france, we have a joke about a cop trying to get intels about high-schoolers actions, he started a sentence with “Bismillah c’est les ténèbres”, that can be translated in “Bismillah it’s the shadows”. Since it’s used as a joke in protests. Some people find this funny, and other people find this islamophobic, I don’t have any opinion.
