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).
Boy #1: look man, that girl has juicy thighs with a slim figure!
Boy #2: yeah man, that girl is slim thick!

Skinny but not anorexic and has curves. The perfect ratio between skinny and thick. Some experts believe this to be the ideal figure of the human female.
