"Metel 7emmem Ma'tou3a Mayyto": Lebanese Slang, literally means "It's like a washroom with no running water", probably an expression that was born during the Lebanese civil war, when running water at home was scarce. An expression used mostly to describe people fighting or arguing a lot.

Person 2: "yeah man, metel 7emmem ma'tou3a mayyto this household"
"Be Khsoos ... ? - بخصوص...؟": Lebanese Slang, literally means "With regards to ...?", metaphorically, it is a question referring to something or someone, to express surprise, sarcasm, shock, curiosity, or interrogation in general. Refer to Jordanian equivalent "Shoo Ben Nessbeh / شو بالنسبه"!
