brownchitis
When a person has a deep interest or sexual preference towards Indian or South Asian (brown) individuals. This term should only be applied to individuals who not only have a 'type' leaning towards Indian individuals, but one that fetishizes the culture associated with South Asia.

It is basically like yellow fever but for South Asians specifically.
