Flirting is a big thing in the Arabic culture, here are the most common words used for flirting in Egypt..

1. Habibi
That means my love and that's the form a girl would call a guy, in case a guy is calling a girl he would say "habibti".

2. Rouhi
That means my soul.

3. Omri
That means my lifetime.

4. Albi
That means my heart.

5. Amar

That means (moon) and it is mostly used by guys to flirt with girls.
Arabs love poetry, and because they lived in the desert, there weren't many natural resources to use in their poetry, that's why they mostly used the moon as one of the most beautiful things in their poetry.
