The term Tebu, or Toubou, is actually a relatively late term, but most commonly is tied to the Teda.
However when I say the Teda and Daza are related, it refers to the linguistic group more than anything. The Teda reside in the north, the Daza to the south.
So you friend may well be making the Teda/Daza distinction.
I do think Goran is likely to refer to the Daza although I have to admit Chad is not my area of speciality.
