Aunzuscauk is a term coined by Wikipedian SomeHuman in March 2010, for showing an on their own group focused attitude and bias by speakers of English chiefly as a first language. The latter are known to occur mainly in the Commonwealth of Australia, in New Zealand, in the United States of America, in Canada and in the United Kingdom of Great Britain and Northern Ireland. Historically caused cultural affiliations, and their language since the mid 20th Century having become the leading lingua franca world-wide as well in general as for nearly all specific domains of interest, may lead to a diminished attention for what others can contribute and for their often different needs, an underestimation or disregard of both, and further to discrimination in respectfulness and resistance in acknowledging rights.

The beginning of the term resembles ANZUS, a military organization based on group identification along aunzuscauk lines. The last part reminds of caucasian, an expression of aunzuscauk thought and influence: English needs to be a familiar language before one visualizes white people often of assumed Anglo-Saxon origin when the Caucasus relates to Blumenbach's craniometrically determined race.
The recent term concatenates the two-character derivatives of commonly used names of the above countries, in a pronounceable order that makes clear none needs to be held more or less responsible than any other: It does not intend a political accusation, it names a sociological disorder.

Non-native speakers of English, admittedly including the coiner of the term, may also tend to aunzuscauk behaviour: One may, for instance, forget to search the Internet in one's own or other known languages because one expects more results by English language terminology - in turn less likely to be free of aunzuscauk. This shows aunzuscauk to be an aspect of globalization.
