Osss! From the Japanese word Oshi Shinobu Osu, meaning "persevering when pushed", or in other words: never give up, have determination and patience. At the start of a fight, we shout "OSS" as a way of letting this sentiment out. It is a way of saying to our opponent, "I respect you, and I will work hard."
Took that from Kauaikimonos.com
