What's up my Mother's Spirit?

So, I've learning some arabic slang. I've been learning some phrases in which you say "You're the best, hey man, chief, star" (roughly translated). Hard to translate slang, like idioms. Well, I was going to try to be funny within the language, so I was going to say, "You're the best, hey donkey." It didn't come out like that. I ended up saying, "You're the best, hey spirit of your mother." I know, what the junk? Well, they fell over laughing at me. Mafeesh mesh kelah (no problem). I am starting to see some headway on language. Some encouragement has fallen my way today, so that is always good to hear. I leaving you w/ a pic from the balcony in which I am staying. This is a sandy place, but there are places you find some green, especially next to this river.
