Is it normal that my dad takes the lord's name in vain when watching sports?
Well, when his team is losing.
It is not like a quick "god damnit!" but more like the very gates of hell opened and Satan himself is cursing God.
He will watch a play closely and when his team fucks up (AND is already losing) He will take a deep breath and holler "GOD DAMN IT!" so loud that the walls shake, car alarms go off, dogs start barking, neighbors wonder what that strange thunder was...
Sometimes he will just say "FUUUUUUUCK!" in a disappointed tone.
It is fuckin' hilarious to watch him get so worked up...
But yeah, do normal people literally holler the lord's name in vain just because their team is losing?
