Hi Safaa, nice to see you back at Italki. Here "Mack" is another word for "man" or "buddy" or "dude." It's used in a friendly manner, when you don't know a man's name.

I think it is just his name. Otherwise all I could find was this: Mack Mack has two definitions: A mack can be a person who is smooth, slick, the Best of the Best, a Pimp, a Ladies Man, the guy who runs everything a.k.a. the Boss. A mack is a person who is always flirting and hitting on girls. Almost always successful at it too.

I agree with Jura, it's like saying "buddy", "pal" or "dude" (or "mate" in Australia). It's typically American. Trivia - "Mack" came from the Gaelic "mac", meaning "son", brought over to the US by the Irish immigrants.

yes, I agree - Mack is another name for mate, man, buddy, fellow, chap etc.

The name of a male .
