The word "bargument'' made the second edition of the Urban Dictionary, though the definition is flat wrong. The writers claim a bargument is defined as:

A confrontation physical or verbal stemming from or taking place at an establishment that serves alcohol.

The drunk guy started a bargument with the bouncer and got dropped in the alley.

Not really. A bargument isn't just a fight that takes place at a bar. That's a bar brawl. A bargument, of course, has to be an argument you would really only have at a bar, over a question that can prompt hours of debate.

You can find much better definitions at the excellent urbandictionary.com website. I should challenge those guys to a bargument over the definition of "bargument.''
