THICKOMETER
A thickometer would be an imaginary scale used to gauge the thickness of a big booty honey. Thickness in the thighs, hips, and ass and such. Different scales apply to each woman, so use proportionately. If she's nice and thick (like say, Trina) she gets a high score on the thickometer. Others who don't quite have as much in the trunk obviously will score a little lower. Fat girls need not apply!
"Damn! Ki Toy Johnson (from Outkast's video) has so much ass that she almost breaks the thickometer!
