What does the Japanese word “Oppai” mean?

It means breasts or boobs, most often used in a non formal way, for example when consulting a doctor at a check up in japan they would not use the word oppai; however, a young boy going through puberty in Japan might use oppai when talking about his crush’s breast.

Hope that helped you understand not only the meaning but when and where it may not be appropriate to use the word oppai
