I was always curious to know what the hell Altair say to the guards that makes them so angry ,when they're harassing the citizens on AC1.I found this list bellow
Eghrib an wehjy: Get out of my face .You disgust me. Go away. You make antelopes excrete their inner organs unwillingly just by how repugnant you are.
Waihak: How dare you?In formal Arabic this means punishment and torture. Mostly used formally in the Qura'an.
It basically means "You're in deeeeeep... trouble"...
Rdoha alaih: Try that on me, have at me (ie why don't you pick on someone your own size)
Tamahhal: slow down
Ala rislek: Stop
