A woman whose thighs are so powerful she can crush granite between them. It's so sexy! It can happen to women who march.
The most physically attractive person in the GT Marching band, Thunder Thighs, is really Catherine S., the flautist, who graduated in '08.

a girl with perfect hips and thighs and knows how to rock a bikini. Usually has the best body out and goes perfect with abs. Thigh gaps arent even needed if you have thunder thighs, your basically perfect already! be careful not to judge people by this, and dont use it against them.
thunder thighs are the opposite to fat so dont make it out to be
