Of course it does!  Haven't you ever noticed that fat people always have a resting bitch face that makes them look like they're just angry at the world and hate themselves?  I always took it for granted until my man (whom I have turned into a grade A shitlord!) pointed it out to me one day.  "Ever noticed how fat people's faces always look miserable" he said to me, and now I consciously can't stop seeing it!
