When the two cords in the back of your neck look like an eleven because you have become too thin. meaning your time on earth is short. From the Mel Brooks classic movie "Life Stinks" for those of us old enough to remember the character Sailor's explanation. Later in the movie Sailors elevens were up.
Sailor: Pops ain't gonna be around long his elevens are up.
Pepto: What!!
Sailor: his elevens, look at the back of his neck see those two cords sticking up, they make like an eleven, once there up that's it he is a goner.
