To call an incomprehisible play in a football game (when a more humble approach is more prudent) costing your team points and possibly the game--as with Bill Belichick's decision to go for it on 4th and 2 on his own 28 with a late 6-point lead against the Colts.
Nick Saban should have just punted on 4th and 23 in his first possession of the game, but his ego forced him to Belichick it with the fake, leading to a field goal for Texas.
When you have to pee in a movie but don’t want to miss anything, and must do the following mental equation: will the amount I have to pee cause enough discomfort to diminish my attention capacity for the remainder of the movie to an extent which is greater than the amount of the movie I would miss by making a mad dash to the restroom.
I saw Satantango last night, wonderful film but by the 5th hour I had to start doing pee calculus.
