MMB (noun): Moshi Moshi Bum

A word originating from Sydney in 2003, MMB is derived from a combination of the japanese word for hello and the word, 'bum'.
MMB soon evolved to be a nickname that was used as a fond term for the person it was addressed to. MMB has great sentimental value for the two friends who started it and it was to be the word that would initiate years of great memories.
Usage of the term was frequent in emails and xanga comment boxes.
