Fekk 3anneh - فك عني : Lebanese Slang, of unknown origin. Meaning: "Get your grip off me". This slang is used when someone is annoying and you want to rudely ask him/her to get lost!
Egyptian Slang. literaly means: "With the mother of Terter". Used to sarcastically indicate that what a person thinks or hopes is impossible. Since Terter (means: shiny beads usually decorating Egyptian dancers' traditional outfit) is not a name you would find associated with anyone so it is very difficult to find "Om Terter" to get what you need from her.
Other Variations include: 3and Om Hanas, Om Elteet, Om Bo2bo2 ... etc. The more creative you are in selecting an unusual and funny name the more laughter it will bring
