My French teacher says a couple of expressions pretty often. Some of them I understand, but there's an expression I cannot figure out what it means. The problem is I can't google it because I don't know how to write it, all I know is that it sounds something like bee-ah, and that it is used like a filler, along with c'est a dire. That may be all, or just a part of it. I know it's not much, but that's all I can say.
