He said, "We ain't never going to lose to them. They so poo poo. Y'all can tweet that."
He wasn't saying only that the team played like crap. That would be a one-time thing. That first part shows what he means. He was saying the program as a whole is crap. It's much more of a swipe at BYU than you're implying.
But, not that big of a deal, either. I do hope he never wins another game, though.
