Japanic = half janapese, half hispanic

How do you tell someone nicely to shut the hell up and to never talk to talk to you again ever. I work with a moron loudmouth loser who lived in Japan for 4 years. She has been back in Canada for six months but all she does is talk about Japan loudly. I have never shown interest in Japan or anything she is saying, in fact I often put my head down and look/fix my shoes when she talks to me. I can be talking to a buddy about hockey and she will come over and interupt and tell us the Japanese word for stick and then she will continue talking about something not at all related to hockey. I just want to know the Japanese word for "God damn it, shut up and go roll up into a mossy log and suffocated your self on your own useless rambling". The biggest problem is that she speaks so loudly that nowhere in the store can you get away from her voice. The only place to go is to hide in the basement. Who the hell cares about Japan. Its the only country she has ever been to as well so now she is the big world traveler and all cultured. Why are there so many people in the world oblivious to reality.
