Ciao was originally an Italian word meaning 'hello' or 'goodbye', but culturally diffused into various European nations with Romance languages.
In the United States, it is commonly used by Spanish-speakers and
French-speakers, in addition to Italian-speakers.
When "ciao" is used by
Americans, instead of looking sophisticated, they look like retards. So, if you'
re American.... just don't say it.
Spanish: Bueno, Mamá. Ya me voy. Ciao!
French: Alors, Maman. Je me vais. Ciao!
(OK, Mom. I'm leaving. Bye)
An American saying Ciao: Ciao,
darling. I'm a prick because i say 'Ciao' to sound sophisticated
