Globally, Bubai (Bubai 
, 不败 
) is a common predominantly boy's, but very infrequently feminine forename. The forename Bubai is characteristic of India, where it is quite a rare principally boy's, but very seldom girly name, United Arab Emirates, where it is a rare male name, and Nigeria, where it is a very rare principally male, but scarcely female name. Not in comparison with a country's population, it is the most numerous in India, Nigeria, and China.
