[Teresa Edgerton]

Well, that list is great fun.

However, while all of those words more or less mean nonsense, they describe so many different shades and flavors and shapes of nonsense (and nonsense of so many different intents and intensities) that I think most of them aren't really interchangeable.

How about some definitions for the ones that are not interchangeable?

Such as:

drivel childish, silly, meandering talk

malarkey something said or written with the intention of misleading or impressing; bunkum

quackery something falsely presented as having curative powers, like a patent medicine; a pretense at medical knowledge, like a snake-oil salesman

flummery foolish or empty compliments

falderal a trifle, a bauble, a gimcrack, a geegaw, something uselessly gaudy
