Cornshark 

Popular phenomenon of an Asian female obsessed with obtaining only an Anglo-White male boyfriend as arm candy. Or Corn Fed (All American White Male). This is usually done without any regard to culture lines or racial differences. The term is in reference to the FEMALE in all situations and contexts. Cuz hey, a mans gotta do what a mans gotta do. Regardless of HER race.

Orange County California and San Diego California are prime Cornshark habitats and breeding grounds.
