A sexual preference of non-Indians for denizens of the Indian subcontinent, particularly after India's sudden rise to power, following the economic boom of the early 21st century. The "customer support" moniker stems from the fact that people who call Customer Support for large software companies will often end up speaking with an Indian person.
White guy: Have you seen Aishwarya Rai? She is freakin' hot!
Asian guy: Man, you've got a bad case of customer support fever!
Customer Support Fever is a type of ethnic sex fever, similar to Jungle Fever ("Once you go black, you never go back") or Turban Fever ("It's the oil"). Indians are the targeted group. The name comes from the people normally manning (or womaning) call centers.
