(Noun)
The dimensions or magnitude of a female's breasts. Because breast size is considered important in assessing someone's attractiveness, and because it is sheer impossible to measure, it is the subject of immense speculation by both heterosexual men and women themselves.
For
simplicity's sake, we usually talk about
bra size. Bra sizes consist of a number, indicating the length of the band, and a letter, indicating the volume of the cups. Most men don't bother about the number and just focus on the letter instead. AA stands for really small breasts, whereas D, DD, E, F, and so forth signify there's a LOT of weight on a girl's shoulders. The letters, however, are misleading, because the cup
sizing moves along with band sizing. The volume of 30F boobs is actually the same as those of 34DD or 38C.
That's why practical men have moved on to more natural indicators of size. A handful is one of the most used measurements because it is both personal (your
hand size) and universal (we all have hands).
An additional obstacle is the fact that you only seldom get to see someone's naked breasts, and that the true size is obscured by nifty contraptions known as bras. A good
push-up bra can get a lady with A cups to show off cleavage, whereas a
minimizer bra does the exact opposite for someone who has big breasts.
Another but related concept is
breast shape.
