b cups - The size where your boobs are just barely bigger than your n

The size where your boobs are just barely bigger than your nipples, and that's about as big as it gets.

My brother said, 'I got B cups, and I'm just barely bigger than my nipples.'

I told my friend, 'Your B cups are just barely bigger than your nipples.'

My crush texted me, 'I got B cups, and I'm just barely bigger than my nipples.'
