Lebanese Arabic. Most curses are about female relatives, because female relatives are “sacred”. People would literally kill you for it if you aren’t extremely close friends, and even then some people don’t accept it.

The most common curses are “Kiss emmak”, which translates to “Your mom’s pussy”, or “Kess ekhtak”, which means your sisters pussy. That’s it. That’s the curse you’ll get your teeth knocked out for saying. You add a “Kess emmak b ayre” to it for more effect, which means “My dick is in your mom’s pussy”.
