I’m no sure that wigger is “offensive” (at least in the same way that the word it is patterned on is offensive). While it is derogatory and mocking, I don’t think the use of the term would brand one as a bigot. Also, it seems a bit euphemistic to say that wiggers adopt certain aspects of African American culture. A white man who had a master’s degree in African American studies and a deep appreciation of Jazz would not be referred to as a wigger - an upper middle class teenager who wore a baseball hat sideways, his shorts barely above his ankles, and who said “hella” and “gangsta” every five seconds would be. Perhaps, “youth who superficially parrots certain aspects of hip hop culture, as depicted in rap videos and other media” would better capture the sense in which the word is used.
