whitebread

Belonging to the class of bland, clean-cut, middle-of-the-road suburbanite breeders. The Cleavers from the old TV show "Leave It To Beaver" are a familiar archetype of whitebread culture. Compare to yuppie.

The term implies profound cultural naïvete, blind consumerism, and an unquestioning "follower" mindset. Common trappings of the whitebread lifestyle include golf, Kenny G and Enya CDs, SUVs, an irrational fixation on lawn care, Golden Retrievers, nominally Christian religious beliefs, Old Navy clothing, moderate to conservative political views, bad Chardonnay, equally bad espresso, cookie-cutter houses, Bath & Body Works hygiene products, and very white-collar employment.

Though whitebread individuals are usually white, the term is not necessarily racial in meaning - the implication lies more with the blandness, predictability, and banality of plain white bread. Accordingly, "wonderbread" is often used as a synonym.

Whitebread, a predominantly or all white community, usually live in rural areas but not always. Anyone who is ethnic (including African) in appearance even in the slightest way, people will stop what they are doing and stare. Racial slurs may be spoken as a part of day to day talk and people will treat anyone who is not white as an outsider.
The phenomena of Whitebread occurs as white people in these areas are only breeding with other white people, thus the term White-Bread.
