Well I do use this word all the time. It's another form of saying hello! Or hello and yo mixed together.

1. A greeting based on the greeting, "hello." Heyo is meant to be a more positive alternative to the monotonal "hello" and simple "hi", optimally used when said in exclamation but not necessarily since the greeting still implies this when said in a normal tone.
NOTE: Heyo when used in this manner is NOT meant to be a combination of the greetings, "hey" and "yo".
Jon: Heyo :D
Nick: Hey, what's up :D?
