Actually she (or you) did. 130 lbs total minus 72 lbs of boobs=58 lbs of her without the boobs. That is unequivocally horse shit.
Aha, now I see where this figure comes from.
For the sake of comparison, I thought it would be handy to give yet another figure: one indicating underweight. Unfortunately, this is not easy to do as there is no agreed upon measurement. But I guess it is fair to say that, given the size of Beshine (5' 6''), a total body weight of around 110 lbs or less would indicate underweight.
As said, this refers to 'total body weight' - there is no indication for total body weight minus total boobs weight ...
