I enjoy seeing how butt obsessions can differ with older generations. One time I heard my dad mocking his girlfriend about having a big butt and he was slightly disgusted by the notion of a big butt.
My dad is definitely of that
1980's white guy stereotype that likes big tits and an ass you could use as a pool table. I actually wonder if, as racism has slowly eroded from everyday life, the big butt has become less of a stigma.
I remember in high school the girls I knew were obsessed with losing their butt weight too.
