Cumsi cumsa

I don't know how to spell it right but it goes "cumsi cumsa" need to know meaning and origin

Ooh, la, la! That one is French, to wit, "Comme ci, comme ça," meaning "like this, like that." In English you could say, "Oh, up and down," or "So-so" or, "This way, that way." How to translate it depends on the question. Perhaps someone whose French is better than mine can give an answer better than mine.
