noun
lack of Japanese language support in Japanese-made content
Internet slang, abbreviation of お前の国にも売ってやる、ただしお前の国の言語抜きで ('We'll sell it in your country too, but without your language'). Used especially for video games and software where the Japanese version has Japanese language support but the overseas version does not.
