Overused by people who want to attempt to make up an "Asian Name." I read books with supposedly "Asian girls" whose names are Mei-Ling, Mei-Chen, Mei-Tang, Chin-Mei, Chang-Mei. It gets annoying after a while. I know that this is supposed to be a popular girls' name in China but in my Chinese school years, I've never heard of a student with "Mei" in their name at all!
