In all the world, Rittidech (ฤทธิเดช , Rittidech ) is quite a rare predominantly masculine, but very infrequently girly forename. The forename Rittidech is characteristic of South-eastern Asia, particularly Thailand, where it is quite a rare principally masculine, but scarcely female name. Likewise, Rittidech is the last name as well as the forename.
