Guera

[Britney]

Mexican-Spanish slang for a white girl or light-haired girl. It is a jargon from Mexico that is also used by Chicanos within the United States. English-language speakers who are not familiar with the origins of Spanish words (or dont care to become educated about them) can become misinformed into believing that one cultures mumbo-jumbo is widely accepted by other Spanish-language societies. Guera (or Guero, for males) is not a word that is familiar among native-Spanish speakers from countries such as Cuba, Santo Domingo, Puerto Rico, Chile, Argentina, etc.

[Rihanna]

A term used for Latinas who have a fairer complexion and lighter hair/eyes than their more darker Latina counterparts. It is not the same as a gringa. It is important to note that in the spelling there is an umlaut above the letter u giving it a w sound, pronounced like weda. Can be either derogatory or complimentary given the circumstances. The masculine form would be guero.
