N.B.R.
the size comparison between your areola and your whole breast, like it's the most important thing in the world.
'She's got the best N. B. R. I've ever seen. It's like a whole pizza next to a slice.'
'He stared at her chest for five minutes just to measure the N. B. R.'
'I got judged on my N. B. R. and failed because my areola is too tiny.'
