Part of the word inflation (or body inflation). Like mostly for girls only, you're inflating her breasts, or she self-inflates her breasts like a twin balloon. In fantasies, the limit of the sizes is rather than a house, maybe a big apartment, or even infinite.
"You: Do you love it? You love inflating your own breasts like a balloon, right?
Your girlfriend: U-Uhhn~... Y-Yes... I have a love for it, just like I was a balloon girl. Can I inflate my breasts... Even bigger? Maybe infinite? I-I'm eager to explore and feel it even more... ♥
You: That's why breasts inflation is good for you..."

A Rule34.xxx tag with over 1.6 million posts, mainly because most people like big breasts and even larger ones. Also an alternate word for large breasts, but the term "large breasts" came way longer than "big breasts" does.
If you search this up on r34xxx, you'll see posts with this tag even though the Rule 34 wiki definition states that it was smaller than the head, are full of huge ones, or even hyper ones.
Outside of Rule34.xxx, it's also said twice by Turkey Tom in his "Puppychan: Artist Insanity" video.

A lot of people like big breasts, because they find them hot. Not all people like them, some people like small or medium ones.
