As a student many years ago, I shared a workspace for a while with a Syrian student by name of Mahmood.
He was wary of me at first when he learned that I’m Israeli, but mellowed when he saw that I bore him no ill will. He only really relaxed, however, when I revealed to him that most of our swear words in Hebrew are Arabic.
‘Really?’ he asked, , intensely curious. ‘Give me some examples.’
So I told him of some of the obvious ones, such as k** u****k and in**-abuk (this is a family website, so I won’t spell them out), and more flowery ones, such as yaḥreb beitak. I also told him that there are Arabic expressions that we use not for swearing, but just as slang—such as tizzi**bi.
