#2 Bray Wyatt will throw hints about other characters, through a word every week
I could certainly be wrong about this, but this has Matt Hardy written all over it. We all know that Matt Hardy and Bray Wyatt are the best of friends and were even RAW Tag Team Champions at one point. So, there's always the possibility that Matt Hardy had a say in Bray Wyatt's repackaging.
I've interviewed Matt Hardy and he told me that he is influenced by films such as Deadpool, where everything is seen through the lens of irony. I'm drawing the parallel because the 'word of the week' concept has also been used by him previously. The 'Woken Word of The Week' gimmick was a big hit on Twitter back when it was used by him.

But by using the word 'sociopath', Wyatt told us that there was a dark underlying theme to this whole shtick and yes, I love it. Matt Hardy would call it 'wonderful'!
