japanese trap 

A japanese trap is a character in an anime where that characters gender appears to be that of a female but in actuality the character is male.

"While watching some Japanese anime, I thought the lead character was female. Later on I found out "she" was a japanese trap, with a really long cock."

Japanese Mouse Trap 

A hold that will trump even a full nelson, that requires the victims nose to be squeezed between someones buttcheeks. The hardest part of the hold is figuring out how to get the persons nose in striking distance, which often requires some trickery, but once the cheeks are clenched, you will find the owner of the nose at your will and unable to break free.

John: "Why were you at that party for so long last night?"

Dave: "Someone put me in a Japanese Mouse Trap and wouldn't let me free"
