Nothing is worse than a fat bitch with confidence 
That is often a control issue.
They ACT confident. They like to portray that they are in control.
But, in actuality, they are not.
In fact, most times, the very fact that Fats think they are 'all that', or whatever, belies what they really feel inside.
That they are not in control.
I must say, if I am watching , let's say, a financial channel, and they have an 'expert' on who maybe is extremely successful in his or her field, and they are obese...
...Then I don't believe their success.
THEY don't believe their own success.
True success comes with comfort...and the successful endeavor provides the comfort and well being.
Overweights usually seek their success and comfort through overeating.
