About two years ago I watched some old Monty Python interviews. In one of them, Graham Chapman, a Brit, makes fun of Terry Gilliam (the only American) for his lack of vocabulary. He specifically cited a moment when the group flew over the great lakes and Gilliam said "there's a bunch of water".
I found this amusing. But it's also stuck with me. And ever since, every American I meet with seems to have an affinity for saying "a bunch" to describe anything with a high quantitative value.
This can be anything from purely literal (a bunch of parsley) -- though this doesn't bother me as much -- to the generally "many", such as "a bunch of candies" and almost sarcastically as in Gilliam's case (obviously several thousand cubic miles of water is a bit more than a "bunch").
But what is a solid alternative for these uses? Not that I'm looking for something to replace "a bunch" entirely. I find it can be useful and an endearing "Americanism". But I'd like to hear of some options.
EDIT: Maybe I can make this more specific and ask this: What would an appropriate British expression be for the Gilliam scenario above? Maybe something like "A Considerable Amount"?
