Or an old man is having PTSD based on years of abuse from a guy named Austin? Again I'm all but certain Vince said this (maybe not PTSD specifically but he said that the "Austin" part of his name reminded him of Stone Cold).
I'm not saying it was a good idea. I hated shortening the name because Theory is a regular word. But unlike virtually every other name shortening this one had a reason behind it, which made the act of doing it better. Better than just hearing "Big E" without the Langston, "Cesaro" without the Antonio, "Rusev" without the Alexander, etc.
