I get what he's saying. When women gain a lot of weight and their titties balloon in size, the reverse happens to their tits when they lose weight, giving once huge titties a very deflated look. It doesn't always happen, but it can. Happened to one of my close friends. She got "thick" after some weight gain, lost a fair amount of weight due to stress, and her tits looked deflated and saggy after. She ended up getting implants.
