The Many Meanings of MBA

Ever since my brother started preparing for MBA, we've encountered several new definitions of the same.

The Original: M.B.A : Masters of Business Administration

The Gujrati M.B.A : Manne Baddu Avechh (I know everything)

Dinky Uncle's M.B.A: Marriage, Bhog, Anniversary.

Dinky Uncle is my ex-neighbour, now living in Chandigarh, who is quite often obligated to attend several social functions, travelling across north India to attend Marriages, Bhogs (something like Chauthas), and Anniversaries of his several contacts. Thus, he is self-styled M.B.A

Does anyone else have any more fun definitions of M.B.A? I'm forgetting the rest I've heard, and would love to be reminded.
