to use the word "execut**n" then you are probably someone who doesn't really know sports. That is a Bronco brainwashing word that I often choose to believe he only uses as coachspeak--but I think I know better now after all these years. But when fans use it, yikes, that's just embarrassing.
And no, no other coach that BYU fans follow uses that word nearly as often as does Coach M. So no arguing that "lots of people say it" because it's just not true.
