death alley

An entire corner or row on a Monopoly board that is owned by one person, has nearly maxed out hotels, and requires either extreme luck or thousands of dollars for others to pass.

Luis was approaching death alley, and would likely lose unless he rolls a 5, a 7, or a 12.

pit of no return

That little hole in between two car seats, where once something falls in, it is way too difficult to retrieve.

Some of my coins slid into the Pit of No Return the other day, and I gave up trying to get them back after 20 minutes grueling effort.
