It's bizarre to hear a woman prefer to have a flat ass instead of a full round ass but white girls weren't as into having big asses during that time period.
I don't think you realize how big of an impact Hip Hop has had in changing white men's preferences. Big asses were considered unattractive back then. When white boys said a girl had a fat ass it was meant as an insult.
shyt has done a 180 nowadays. Our preferences are now what's in. And I'm gonna give that credit to the spread of Hip Hop music.
