ciao a tutti, belli e brutti
(hi / bye everyone, the pretty ones and the ugly ones) •
It is a rhyme expression used to greet a group of people. It is similar to "See you later, alligator" but it can be used both when you arrive and when you leave.
"Io vado. Ciao a tutti, belli e brutti."
"I'll go. Bye everyone, the pretty ones and the ugly ones."
