The Indian Tsunami is when an Indian man and an Indian women are having intercourse and the girl orgasms causing pussy juice to form, the man's penis would still be in the pussy at this point, causing the pussy juice to build up. When the man finally decides to take out his penis therefore causing the pussy juice that built up to shoot out.
