1. A reference to a woman hot is both hot (attractive) and Asian.
2. Slang used on an east coast audio podcast show, The Jone Dome, to refer to an Asian woman who is attractive.
Derived on the basis that Asian women are generally attractive, so a hot Asian is a redundancy.
See also, half-a-redundancy which refers to a woman that is either hot or Asian, not both.
Ex.1: Lucy Liu is a total redundancy.
Ex.2: Let's go down to Chinatown and scope out some redundancies.
Ex3. Yeah, she's hot, but half-a-redundancy
