The thumbs up is a common gesture all over the world. A long time ago it was the one with which the emperor decreed the life or death of a gladiator. Today, thousands of years later, at the time of social media, the raised finger indicates appreciation even more: the like, or "o' like" - as we would say in Naples. But be careful, just flip the thumb 180 degrees to get the opposite meaning.

In short, you can use the thumb of the hand as you wish, to indicate many meanings. As you want, as you like. And nuje likes it accussì! Co 'o like!
