Miss White of the WFSU crew AKA Karena's definitions

thass

thass; the area in which your ass and thigh join as one. there should be definition between the two, a thigh... then your ass, creating a "shelf" if you will. but when you start to gain weight you loose that definition, thus creating the infamous thass.
