"Morta di fame" is an Italian phrase which literally translates to "Dead of Hunger." It denotes an utterly useless, stupid person. The connotation is that the person is dead from hunger due to the fact that they are useless and thus can't do anything productive to earn money for food to eat. "Morta di fame" status is usually accompanied by mouth-breathing and general slow-wittedness.
Mirta is a gorgeous girl, always surrounded by a bunch of guys who are following her arround like dogs. Mirta is very outgoing and not afraid to say what she thinks. She can light up every party and she has a bombass sexy body. She is confident and aware of her beauty, which is why some people are too shy to talk to her.
But once you get to know her, you'll find she is an amazing friend, who is always there for you and puts others before herself.
Only the kindest people deserve to have a Mirta in their life.
"Dude, check out this girl! She's definitely a Mirta!"
"Man, this girl I met is the kindest person ever! Bet she's a Mirta?"
