n.— «Dirty Sanchez is just one of many sex acts named after a locale or ethnicity, in a subgenre of slurs linguists call “ethnicons.” These are insults meant to comment on an ethnic group’s supposed depravity that become popular shorthand for said characteristic—for instance, we call vicious people “mongols,” “welsher” is synonymous with a swindler.» —“ ¡Ask A Mexican!” by Gustavo Arellano Orange County Weekly (California) Jan. 5, 2006.
