squeaky bum time
n.— «The pair are on one-over and in need of the win. Harrington’s position is almost as simple—first or second if Casey is in the top 35, third if he finishes outside it. At the moment Casey is tied 35th. Yes, it truly is squeaky bum time here.» —“Harrington’s stomach for fight shines through” by James Corrigan The Independent (United Kingdom) Oct. 28, 2006.
