mafi mushkila

Means "no problem" in Arabic, it can be used in its literal sense to mean "no problem," or it can be used in a figurative sense to me "there's a huge problem, I don't know how to fix it, I'm not even sure how big a problem it is, but I'm not going to tell you until I figure out my next steps." Usually delivered in an amiable tone with a can-do attitude. The next step beyond a mafi mushkila-sized problem is mushkila, which means "this problem is so big I'm not even gonna bother trying to hide it."

There's water spraying onto your electronic equipment? Mafi mushkila, I will sort it out.

You need to be at the airport in twenty minutes? Mushkila.
