to blow a lead in a game with minutes to go, typically caused by an awful, horrible, grotesque, beastly play call.
Beargina #1 - "Well, we are on the 20 yard line and its 4th and 2. There is just a minute to go and I have no time-outs, so if these guys score I will be completely and utterly fucked and have no means to answer their touchdown, therefor losing the game and causing my whole team, management and fan base to loathe and despise me for years to come. Might as well go for it, right?"
(turnover on downs)
Beargina #2 - "Wow, you really fuckin' Bellichick-ed that one didn't you?!"
