Sumo Wrestler
noun
A power samurai isn't a samurai at all. A Samurai's all about precision, after all. So, imagine someone that's a huge mass of muscle (and fat). This Japanese warrior is all about power... ramming into people as hard as they can to knock them over. This person is a sumo wrestler.
This is a jukugo word, which usually means on'yomi readings from the kanji. If you know the readings of your kanji you'll know how to read this as well.

If you want a sumo wrestler's autograph, why don't you go to Ryogoku?
