When do you draw the line???

Ok folks I got a questions that is up for much needed discussion...Me and my homegirl was sitting around just talking and looking on myspace and all of these girls on there calling themselves "THICK", "THICKNESS", "THICKWIT IT", "THICKUMS"ect.....Now granted some of these girls on there had nice shapes to say the least but the rest, well thats an understatement MOST of them were well what we call, "OBESE", "CHUBBY", or just plain FAT. Now, I'm not the type to down, or hate because you as a person are entitled to you very own opinion but I must ask, WHAT IS THE DEFINITION OF THICK??? Meaning, I want to know sizes, measurements, weight class. Whatever it takes to make me understand the meaning of this whole THICK CRAZE we going through now a days.

PLEASE YALL I REALLY WANT YOUR INPUT SO....STR8 MEN, GAY MEN, Bisexuals, YOUNG, OLD, WO
