I think this is an interesting aspect of the more generalized contempt for all women. Men like this view women as existing either for sexual stimulus - “eye candy” - or sexual use. Women who don’t “serve” because they’re fat, old, disheveled, or handicapped, or because they’re modest, chaste, ladylike, or mothers, can be openly ridiculed like this.
However, they don’t respect the “hot” women who provide them with free sex, either. If the lads weren’t saying women in S.A. were fat, they’d be talking about how they were sluts.
Women, including fat women, can almost take pride in being despised by persons of this ilk.
