All around the world, Pibun (พิบูลย์ 
, พิบูล , Pibun ) is quite a rare principally boy's, but scarcely feminine first name. The forename Pibun is characteristic of South-eastern Asia, particularly Thailand, where it is quite a rare principally boy's, but scarcely female name. Very seldom, Pibun is the last name as well as the forename.
