n. pl. Wapanese
1. An individual who embodies the general characteristics described above.
Also known as a "Gaylord".
2. The official language of the Wapanese. It is essentially the english language supplemented by the limited knowledge of Japanese to replace regular english words for no reason whatsoever.

Guy 1: "You know, Billy's been acting really weird these days. His hairstyle now makes him look like a Dragonball Z reject. When he isn't saying "ne?" at the end of interrogative statements he's too busy stuffing pocky in his mouth and attending anime and cosplay conventions. All whilst striking homoerotic action-poses and washing it all down with pocari sweat."
Guy 2: "That's a totally fucking wapanese thing to do. I hope he gets hit by a truck."
