People are now signing their posts with Oss.
When it was Karate, I could understand because it is something ingrained in some karate clubs.
It is part of the roots for Kyokyshin Karate for example.
Sensei said something: you replied Oss.
You greet each other at the Dojo "oss" etc...
But nowdays, I noticed such tradition has creep into the BJJ world or more like the internet.
It is ridiculous to read someone that train BJJ with Oss for its every posts.
I suspect they might even Oss each other on the mats. lol
Why are they copying someone else traditions?
Maybe they are looking at getting TUF.
Well anyway a good read on the real OSS below:
The Spirit of Osu
Osu is a contraction of the words:
Kyokushin training is very demanding. You push yourself until you think you've reached your limit. First your body wants to stop, but your mind keeps pushing you. Then your mind wants to stop, but your spirit keeps you going. You endure the pain. You persevere. That is Osu.
Kyokushin karate is not learned overnight. It takes years to properly learn the fundamentals. The basic techniques are performed thousands of times (Renma 錬磨 – "always polishing") until they are done by reflex or instinct, without conscious thought (Mushin 無心 – "no mind"). It's easy to get frustrated by doing the same thing over and over again, especially when progress seems to be slow. To overcome that frustration and continue training takes patience and determination. That is Osu.
The absolute and unfaltering devotion needed to "scale the cliff" of Kyokushin karate is Osu.
The spirit of Osu is probably best described by Shihan Cameron Quinn of Australia in his book The Budo Karate of Mas Oyama. He writes:
There is a saying in Japan, "Ishi no ue ni mo sannen" 石の上にも三年. Translated, it means "Three years on a rock." This saying symbolizes the need to persevere at all times. It is one of the most important philosophies in Kyokushin karate.http://uskyokushin.com/osu.htm
Kyokushin is an art offering many things according to the immediate and long term aims of the trainee. Ultimately, one realizes that transcending the kicks, the punches, and the kata, there is a special spirit in the heart of the participants. It teaches them to face the demands of daily life with a mature and enduring attitude. A Budoka 武道家 is not easily shaken by the blows of adversity, realizing that for a person to draw near to their true potential, a never-say-die spirit of perseverance is required.
This strength of character develops in hard training and is known as Osu no Seishin 押忍の精神 (the Spirit of Osu). The word Osu comes from Oshi Shinobu 押し忍ぶ, which means "to persevere whilst being pushed". It implies a willingness to push oneself to the limits of endurance, to persevere under any kind of pressure.
The single word Osu captures most accurately the ultimate in what the art of karate, particularly Kyokushin, has to offer. One who is truly able to manifest the spirit of Osu in every word, thought, and action may be regarded as wise and brave. Training should first and foremost be approached in the spirit of Osu. One's daily life, and the responsibilities it holds, would be more completely lived if addressed in the spirit of Osu.
Even for the beginner, who is conscious of his lack of training and does not necessarily want to face the demand of training, it is enough merely being aware that through perseverance and the will to continue, there comes great physical, mental, spiritual, and emotional gains. All that is needed is that special determination."
