Purple Dragon Don Jitsu Ryu

I am a purple dragon student! I have a white belt! (I'm a bottom-feeder!) It's super fun! Except that I can't seem to summersault in a straight line. And my thighs hurt a ton. Like, a TON. Like, I'm walking and afraid they might stop working all together and I'll collapse hurt a ton. The etiquette is hard to get used to. Bowing at all the higher ups, bowing at the floor every time you get on or off of it, bowing several times just to get in the front door. Every time you bow you say "Ush." After nobody could explain this to me and I knew it wasn't the Japanese word for "yes" as they claimed, I googled it. It seems to be a bastardization of the word "osu," or "os" as the 'u' is often silent on the end of Japanese words. One internet source says: " When you enter or leave the dojo, you bow and say "Osu". When you greet a fellow Kyokushin Karateka 空手家, you say "Osu" instead of "hello". When you respond to an instruction or question in class, you say "Osu" instead of "yes" or "I understand". When performing Kihon Waza 基本技 (basic techniques) in class, each technique is often accompanied with a loud "Osu". When practicing Jiyu Kumite 自由組手 (free fighting) in class and your opponent lands a good, hard technique, you say "Osu" to acknowledge your opponent's skill. As a measure of respect, knockdown fighters at a tournament bow and say "Osu" to the front, to the referee and to each other, before and after the fight." (http://www.uskyokushin.com/osu.htm) Another has a similar explanation: "In Japanese the word oss is written as a two-character combination. The first character means “to push,” and the second means “to suffer.” Together they symbolize the importance of pushing, striving and persevering while suffering through whatever difficulties, pains and hindrances are encountered along the way. So, at the literal level, oss is simply an affirmation of the positive attitude, high spirits and refusal to quit that all karate people seek to develop as they train. On a deeper and more general level it might be translated as “keep the faith,” in the sense of karate philosophy and goals. " (http://www.minrec.org/wilson/pdfs/Language%20-%20The%20'oss'%20greeting.pdf)

So basically, every time I walk in the door I have to say "ush professor (his style everyone is learning, runs everything), ush shihans (seconds-in-command), ush sensei (owns/runs individual dojo), ush senpai (sensei's second), ush instructors, and ush san, bowing each time. I hate this, too. First of all, professor in Japanese is kyoju, and hanshi is grand master, so why is he called professor? and why are the black belts called instructor? Can we stick to one language maybe? pet peeve. Other than silly things like that, I really do like it. Even though it makes me work hard. I guess that's the point, a little hard work and discipline are good for me! So wish me luck while I try to ignore the mixing of languages and work my butt off for the yellow belt! Hopefully another month or so!
