Wow, without proper definition we cannot even have a discussion.
Bbwhunter is wrong. She would be appalled to hear someone call her a BBW , BBWs are fat, fat girls call themselves BBWs , there are even BBWs modelling , some are like 300lbs.
The girl you are referring too is not even 'thick' . She may be slightly meaty or toned, thats it. Then theres Amazon like reffers to taller , thicker girls. Best example I know nearby is Jenny J in Tironto at 200 lbs and 6 foot with huge breasts but proportioned. Think if comic girl fantasy girl types.
