Japanese Fan 

When several penises enter one orafice causing the array of men to spread like a Japnese folding fan.

Did you see that gang bang scene? She was totally sporting a Japanese Fan!

Japanese fanboy 

Someone who is of non-Japanese culture but desperately wants to be one, probably watched a lot of anime, and goes to Japanese language classes.

Daksh is such a Japanese fanboy, he was up till 4:30am watching anime.

japanese fanny pack 

When you are making love to a lady and she releases a bowel movement upon your abdomen.

Morgan was over last night and she gave me a stinky Japanese fanny pack after eating Ethiopian.
