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 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".

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.

1. The state of being excessively arrogant or cocky.

2. The act of choking, as in an unexpected loss.

3. The process of karma catching up with a cheater or team of cheaters.
1. Bob was so too 18-1 going into that Tennis match and lost because of it.

2. Timmy was up by 5 points but managed to 18-1 the game away at the end.

3. 18-1 will eventually happen to Barry Bonds.

1. What the Patriots ended up after they got beat in the Super Bowl
