It's a casual greeting that literally means "How are you?" You can use it for both men and women.
Here are some other variations:
* "شلونچ" (shloonch) - This is the feminine form of "شلونك"
* "صبح الخير" (subh al-khayr) - This means "Good morning" and is used in the morning.
* "مساء الخير" (masaa' al-khayr) - This means "Good evening" and is used in the evening.
Keep in mind that Iraqi Arabic, like any dialect, has regional variations. Some people might use other greetings depending on their specific region.
