sticky yen
n.
- The market for hentai games and media.
One of the better kept secrets of the Japanese game industry is that many companies have at some point or other released a hentai game, usually under the guise of a shadow company. I can guarantee you have played regular games by a large company that have under a different banner cashed in on the easy hentai market, or the “sticky yen” as I call it. —JC Barnett, “Gamesmanship - part ５”
