Jennifer: Who doesn't?
She/He is a Hapa
Some hapas have tried to claim that the use of the term is equivilant to nigga in the black community, i.e. that one hapa can refer to another as hapa and it is good, but a non-hapa cannot, and it would be insulting. Most other hapas think these people are retards and are just happy to have something that isn't as patronizing as halfie or halvsie and easier to say than half-Chinese/Japanese/Korean/whatever.
"My dad is Chinese and my mom is black, and so I'm hapa."
"Did you know that Karen is a hapa? I had no idea, but I guess I can see it now."
