Back in the day when my arabic wasnt as sophisticated as it was now, i usually picked up on anything I heard. After hearing the bengali workers constantly using the word "maafi maloom", I thought that this was basically what I should say whenever I dont know anything. Unfortunately i would frequently end up getting into stupid situations like this:
*walking down the street in the university housing area*
Lady: Ya shabab! T3al dageega...
Me: *walks over* n3m
Lady: T3aref wen makaan "Al-hayel ferdaws"?
Me: uhhhh *thinks for a while* hmmm hayel ferdaws.......wallahi maafi maloom.
Lady: Huh? Maafi ish? Ish gult?
Me: Maafi maloom hayel ferdaws.
Lady: Maafi maloom?
Lady: .......inta afghani?
And no i'm not afghani just in case you were wondering. Close, but no.
