For when you're out of insults to call a member of the gay community and don't want to be too obvious, Yaggaf is a word of anonymity. Backwards for, "gay fag".
Word that expresses just about anything, my dood. This word originates from Reedy High School, a school in Frisco, TX. It was created by a student, from the word Yagga, which came from vine (which is deceased).
Originated from rasta background as a term used to express joy or agreement, has now been picked up and is overused by wanabees wanting to be something they are not. Incorrect usage of the term i.e. using it for the sake of it, is highly common and merely annoys anyone at whom it is directed, as is using it to answer your own question or statement i.e. 'Dats a sick tune, Yagga'. In fact using it to anwer your own statement or question simply acknowledges the fact that nobody else was interested enough to answer the question anyway.
