Do you think some thin people say they are fat to insult fat people?

I think some people like to be down on themselves and some of it is for attention.
Cuz why say it?

No normally it’s just a grab for reassurance and compliments, oh of course your not etc.The persons not thinking about the effect on others, which is hurtful if you are fat but they haven’t though about that.

No i think they just used to be thinner and are unhappy.. some fat people are cute and are perfectly happy.. so *sigh* its just personal perception imo..

Fat is too subjective. Technically the term is overweight, and technically almost everybody is overweight to some degree

Nah. You insult fat people by hurling abuse or celery at them. Whichever is lower in calories.
