Fatso is one of many words for "fat". A good sign of being a fatso is when your belly drops below your waist. I'd think that most people would be decent enough to not tell a fat person that they are a fatso, it can be very hurtful.
A sure-fire way of being a fatso is eating all of your meals at McDonald's.
