look up any word, like sex:
White people have the lowest tolerance for alcohol among all major racial groups, and girls have a lower tolerance for alcohol than boys. If a white girl and a black guy both drink half a beer for their first taste of alcohol, the white girl will seem/be significantly "more" drunk. Basically, being White Girl Wasted is when you get really drunk not having a lot of alcohol.

Getting incredibly drunk off a very small amount of alcohol.

Not exclusive to any race or gender. Simply an expression, similar to Ghetto Booty in this regard. ie: Don't have to be "ghetto" to have the booty.
Five open beers; Six drunk chicks...

To be high from ingesting a lot of cocaine. White girl = cocaine. Wasted = fucked up. Many people incorrectly use the term "white girl wasted" to refer to partying heavily with marijuana and/or alcohol, thinking that their inebriated state is comparable to the inebriated state of a high school white girl discovering Parrot Bay for the first time. The use of "white boy wasted" is the correct slang for this meaning, as the term "white boy" holds with it no connotations of cocaine.
