18 - 1 

1.)To come close in an accomplishment only to fail during the last second after coming so far to absolute perfection.

2.)Coined by the 2007 Patriots and their devestating loss during the superbowl against the New York Giants.

1.)Boss: You 18 - 1'ed your promotion oppertunity

2.)Football Fan: The Patriots were going for 19 - 0, but instead made it 18 - 1 due to Tom brady's clutch choke.

18 - 1  

It doesn't matter, nobody cares, so what, meaningless, etc.

In reference to the Patriots 2007 (almost) record setting season.

I'm proud of my new car but all my friends are 18 - 1 about it.

Peyton: I think I might grow a goatee.

Dwight: I think I'm 18 - 1 about your goatee.

The Chicago Bears went 18-1 and won the Super bowl.

The New England Patriots went 18-1 and lost the Super bowl. Sucka!

18-1 

1. The biggest upset in football history (used by patriots fans)

1. I can't believe the patriots only got 18-1. That's bullshit!

2. WOO-HOO!!! 18-1, SUCK ON THAT, BRADY!!!

18-1* 

The New England Patriots had their hopes of completing a perfect season destroyed by losing the one game that counts: The Super Bowl.

Not only that, but they were also caught cheating during the season so even if they went 19-0 it would still always be questioned.

18-1* is the equivalent of epic failure

18-1 

To have everything going in your favor until the last moment. Derived from the 2007-2008 season New England Patriots whose quest for a perfect season was derailed by the New York Giants in the Superbowl XLII.

I had an 18-1 bowling game last night, I was making all those strikes until I made a gutterball at the final round.

18-1 

18-1 is probably one of the most embarrassing records to have in football history. It may be thought that winning 18 games and only losing 1 is a good thing, but when that last game is at the super bowl to a wild card team, it is nothing to brag about.

The patriots went into the super bowl with an 18-0 record. After getting spanked by the giants they went 18-1 and went from "unbeatable" and "perfection" to "embarrassed".
