Throughout the world, Bayyu (Bayyu 
) is a rare principally boy's, but scarcely feminine first name. The forename Bayyu is characteristic of Indonesia, where it is a rare masculine name, Nigeria, where it is an extremely rare gender-neutral name, and India, where it is an extremely rare principally feminine, but scarcely male name. Very seldom, Bayyu is the last name as well as the forename.
