Boobs big enough to barely cup in one hand.

Those C-Cups were nearly a two hand job.

The reason why girls don't need to lose weight.
D-cup is even better!

Girl: Does this shirt make me look fat?
Guy: A bit, but it makes your boobs look sexy! And don't go on any diets, keep your C-cups!

His neck was getting stiff from all the passing C-cups. The cop suggested he put his neck back in his pantz.

C Cup

A breast size that is slightly above average. In America, the medium to larger C Cup sizes are the optimal range of breasts, as they strike a happy medium between too small and too large to adequately grope. By Japanese measurements, however, a C is the equivalent of an American small B, so As are something truly pathetic in Japan.

1: Damn! That bitty got perfect titties!
2: I'd say she fills a C Cup pretty nicely.
