He thought he need a good night out; and was proven completely wrong! He's on parole, didn't get home till 6 AM; and instead of knocking for his lady friend to let him in, he decided to kick the door down. Lady friend is furious for the obvious facts listed above and handles the situation very badly.
She kicks him out, he steals/totals her car, then goes to the bar (mind you, he's on parole) and tells the bartender his troubles.
Point of the song: He knows he messed up big time in all aspects of his life, and just lost everything.
