Definition: A game between a supposed 'dominant' team (Cowboys) and a 'weaker' opponent (Bills) where although all odds are in favor of the superior team to DOMINATE, they succumb to little mistakes [5 interceptions, 1 fumble, a kick return for TD, TO dropped passes] and cause faithful cowboy fans to go into what some would call 'pensive moments' about life, love and football...for example:
1st Quarter
2nd Quarter
3rd Quarter
4th Quarter
4th Quarter 00:02 left - when Nick Folk kicks the winning 53 yard field goal
I'll be honest - I was a little worried there for a minute.
