A word in dialect to describe a beautiful female. It is more commonly used in Singapore and Malaysia. Despite it's meaning,it is considered rude or uncultured to use this word to describe someone.
When you say a person especially a girl is "chio" you are actually meaning the person is bimbo. Pretty,attractive,good-looking but at the same time a stupid, nincompop or airhead. Although many people in Singapore and Malaysia do not know it, this dialect word was used as an insult.
As this word "chio" is used as an insult, I shall not give any examples. You may want to refer to other definitions for examples.
Chio is a guy who's smart, handsome and has many talents. He has many ex's and people who don't know him see him as perfect, which is why a lot of girls like him.
