A combination of the words "white" and wetback. A whiteback is a person of Mexican decent who does not display the stereotypical idiosyncrasies associated with their race; mainly alcoholism, and laziness, and teenage promiscuity. They do not speak Spanish, and attempt to assimilate into "white" culture.

"No way! She's white."
"Nope. She's a whiteback."
"Oh yea, now that I look at her arms, they are kind of hairy."
