I speak Arabic as a 1st langauge but in day to day life as an Israeli-Jew spoke Hebrew more than anything, so...the equivalrnt of "Man" or "Dude" would be "Habibi," meaning literally "My Buddy." Like most Israeli-Jews I spent my adult life as a soldier and so I tended to use the word "Achee" more all thing being equal. It means "My Brother." Both words are the same in Hebrew and Arabic.
"Achee" is idiomatically like a Briton saying "Mate."
These days, past 2 years this month actually, I have been mostly speaking 3 Bisayan langauges (Cebuano, Illongo and Hamtik, which is actually better known as Kiniray-a) since my primary residence is on Mindanao in the Philippines.
My relationships there are highly defined and to my huge extended family I am either Kuya (Big Brother) or some other relative term related to my placement within the familial structure.
To men my age, more or less, with whom I have friendly relationships, we do not talk in that casual sense. I find Mindanao to be maybe 100 years behind the reast of that nation. Our employees refer to me as "Don," or "Sir." English is a lingua franca, even in Mindanao now so "Sir" is used by younger employees.
Visiting in NYC now, here people saying "Man" alot, but since I among Jews 99% of the time, and mostly my Clansmen it is all in Arabic, Judeo-Arabic, Ladion (Judeo-Spanish) or Hebrew.
Lot of words for a simple question, but there is the answer.
