The edge case where it is expected that one would not understand a spoken response of "No, totally" is where the thing it was said in response to both was phrased such that a negative answer could be one of absolute agreement and where the previous thing said contained in it the word totally. This case could give the interpretation that while you more or less agree you would like the word totally omitted from your agreement. Example(leveraged from jasallen's example in another post): Don't you totally want to eat the whole tub of ice cream? As a spoken response in this edge case "No, totally"(yes I very much want to eat it all) would be indistinguishable from "No totally" (yes I want to eat it all, but I am not as enthusiastic about doing so as you are).
