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.
