Part of the joy of watching hours and hours of sumo tournaments on TV Japan is hearing the sportscasters speak about sumo in Japanese. In general, we don't know that many words other than sumo and food nouns. For that reason, while we're watching sumo we tend to notice the most frequently used expressions. The top three on the sumo telecasts are hai (yes), ano (um) and so desu ne (it is, isn't it?).
Mrguy fell in love with so desu ne, which has many meanings and is used with such passion at times.
