The absolute thickest individual possible. Thick in the skull, Thick in the ass, Thick from McDonald’s. This person is pretty much a deity and must be treated as a ruhruhretard. Often the victim of mass-bullying, Thickmeister will probably end up working at McDonalds and losing his life savings in poker games.
Have you seen Thickmeister lately? They’ve really fallen off a cliff since they started working at Dons...
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 ToyJohnson (from Outkast's video) has so much ass that she almost breaks the thickometer!
