A non-Japanese person who has developed a severe affection for Japanese exported popular cultural items, particularly anime, snack foods, toys, video games, and other mass-produced trinkets (while caring little about Japan as a nation or as a people). Such fans are typically young white Americans, which led them to be labeled with this decidedly racially-charged nickname. Although extremely irritating, they are ultimately harmless, as few become proficient enough in the actual Japanese language to actually travel to Japan to become Janks, McSenseis, or etc. The average "Wapanese" should only be given the same weight as that of the Radiohead fan, or similar follower of middle-America strobe-flash trends.
