What is 4th Down?
After a girl rejects you several times in one night, you make one final play to get her in bed, knowing full well if you fail it will mean she wins.
Ben: So how did you end up getting laid by Heather?
Jon: She kept turning me down and turnign me down, so finally I pulled out my 4th down play, put it all on the line, and dropped a pill in her drink. I WON!
Ben: Um, that's date rape.
Jon: Hey, sometimes you have to cheat to win.
