cardiac win

When the Seattle Seahawks play like crap for most of the game, but somehow manage to squeak out a win, often due to a miracle play from offense or defense, or just plain dumb luck. It causes their fans to think they’re going to suffer a heart attack.

Dude, you look stressed! What’s wrong?!
Oh, I just watched my Seahawks pull out another cardiac win. I figure it took a few months off my life.
