I feel bad for A-cup women described as "almost boobs" and that B-cup women are "barely there" even though both are beautiful.
This is a moronic list to be honest and it's not even funny, but I'll let you off since you're obviously young and immature.1

This is based on the outdated concept that D and up is large. Back in the 1950s that was true but for modern bras it's not. People just wear their bras incorrectly. I am a 30F and my boobs are incredibly average sized. Also, F does not tell the volume of my breasts. 40F is 5 cup sizes larger than my 30F.
