Wayne is very good at Metaphors. Chi in some languages means God, hence the name TuneChi or God of tunes. Using a proper beat Wayne can convert good metaphors into Amazing raps. But Lil TuneChi is also his Alter Ego. In Previous songs before he started with the "Lil TuneChi" stuff, his raps were not nearly as good. I think the "His grandma gave him the nickname" crap is a big lie. Its a cover up so people dont see how big of an Ego Wayne has always had. End of story.
