"Nah, NATSUMI'S chubby and thick, but Mimi is slim thick. She's skinny as fuck, but that ass and those titties still poke out, and they jiggle when she runs"
A girl with big/toned thighs, plump booty, normal sized hips AND a flat/toned stomach. These girls are slimmer than "thick girls" but are still considered thick. What really defines a slim thick girl is her big, juicy thighs paired with a slim figure. They can have smaller curves than thick girls (who have an ideal hourglass shape).
