Hi Ayyo, I think you mean oppa, it's used as a form of address from a younger sister to an older brother, or as a girlfriend to her boyfriend. A.

It can be called for... "your elder brothers in your family" or "your boyfriend who is older than you" or "a very close male friend who is older than you" in a friendly way. Also the spelling should be "o ppa(오빠)" rather than "o bba(오바)".

오빠 oppa not obba old brother for a female

Hi there. I personally suggest that you may refer to the information that I previously answered to another very similar question for your references. The corresponding webpage is given in, http://www.italki.com/answers/question/56562.htm Good day. / 좋은 일일 을.

You can say it to your boyfriend also.If he is older than you..
