A fat person. Not someone who has the genetic predisposition for obesity, but someone who, through poor diet and lack of exercise, has become a soft, floppy, pile of blubber.

Side bar: these people are generally the ones who, through moderate exercise, alcohol intake and diet correction can loose the tub...of goo.
Gawd, that is one tubagoo.

So this guy shows up on the date and (she) could not believe how much of a tubagoo he had become!
