Sucker

Yes, he was calling out La Russa, shouting at him and motioning as if to say, "Meet me behind Murphy's Bleachers after the game, sucker!'' - Jay Mariotti, Sun Times

I can't stand Mariotti, but I thought this line was funny. I don't know if Mariotti meant it to be. I mean, we know Mariotti doesn't talk like this. And I know Baker doesn't either. I mean, who says "sucker"?
