text: lu sangu lava lu sangu? what does it mean... i think its latin?   it is an ancient sicilian proverb, lu sangu lava lu sangu, "blood washes blood". so you can say it is latin but not very accuratly.  i found books and some other sites using this phrase so i guess they still use it in italy. what the phrase means is that if you do me harm i will take revenge in the same way. i think now the italians they call in vendetta and i also know that in greece they use the same word.  i will give you an example. there is one man that has a dispute with some other man and on the dispute he goes and kills him. the the son of the dead man has to go and kill the killer. then the son of the dead killer has to go and kill the son of the first dead person and so on and so on and so on.
