Cluck steak is beef jerky. Beef jerky to a cluck IS steak, thus beef jerky = cluck steak. However, the word is almost never used by actual cluck, because that would divulge their cluck status. Clucks use the term 'beef jerky' to describe beef jerky, but non-clucks can refer to beef jerky as 'cluck steak' (and it really doesn't matter if it's peppered or teriyaki).
