Well, Airbus reckon the A380 is now underweight....as a result of them spending lots of money on a weight-loss program.
However, some people will continue in saying that the A380 is "fat", probably until the end of its service life.
Funny - Boeing's statements
here I would think give me the right to say that the 7E7 is a "fat b*stard" until about 2010...
