1. Greeting similar to
Yo, but more
cute and less ghetto. The word is derived from Yoda. (which consequently has no connection to it's meaning) Since the rights to Yoda is
owned by George
Lucas, the word was edited, so to avoid copyright infringement and confusion from "Star Wars" geeks.
2. An answer to a yes or no question in the affirmative or a positive connotation for any random question. Also sometimes stated as yaba, (yeah-ba) which is more similar to yeah and yes.
