Aeo meaning "Hello" often followed with "Bouyo".
Comes from the words "Hey, yo" which
eventually evolved into the one word, "Aeo".
By dropping the H, and putting the Y's together, it looked like 'eyo' which was
pronounced "Ay Oh" and was simply spelled the new way, A E O.
Bouyo isn't ment to mean anything other then to
represent the person being spoken to.
"Aeo, bouyo!"
"Aeo!"
"Aeo, m'bouyo!"
