A person who
feels that they should be from a
different ethnicity, meant in a similar way to transexual.
Generally used by white
people to exoticify and assume entitlement of a culture that is not theirs. Kinda racist.
White
Girl: Hey look at me being all
kawaii and eating sushi, I love Japanese
people, I'm totally transethnic because I think I should be Japanese
Non-racist person: Uhm...that's objectifying and wrong, stop it please. Just stop. No.
