Spanish word, pronounced fah-TAHL, used in Andalucia to describe something, someone, or a situation as royally screwed up; a HOT MESS, if you will.
Situation:

You and a friend are walking down the street, when you come across a hot mess crack whore, and she looks at you up and down as if to cruise you. You look at your friend while continuing on your way, and you exclaim, "Fatal, tio..."

A variation is FATAR (pronounced fah-TAHRR... with a strong rolling R at the end), which makes the situation more exaggerated.
