say /a/,
i saw a subbed episode of an Azudiaoh episode the other day and as the girls were doing the tug of war they started chanting "OS, OS, OS".

As I recall in the English version they're just yelling 'heave ho', so something's up.

tl;dr: what does OS mean in the context of japanese highschool sports?

pic unrelated. I don't come here.. ever.
