When a literary, television, movie, internet, or other source implements a person from African American descent as well as a person from Asian Amercian descent to promote diversity without heavily impacting the story line. They are often closely tied to each other and will occasionally shadow a prominent character.
Just a few quick examples of when the asiack effect is used in television:

Gossip Girl: Isabel Coates and Kati Farkas
Hannah Montanta: Amber Addison and Ashley Dewitt
Dexter's Laboratory: Mee Mee and Lee Lee
