Plural of darndest; multiple instances of extraordinary or remarkable things.
From 'darndest' (superlative of 'darn') plus the plural suffix -s. This unusual nominalization turns the adjective into a countable noun, as in 'the darndest things happen to us.'
Using 'darndests' as a noun is so casual and American—saying 'the darndests happen' is like your grandpa talking; it's wholesome Americana slang that's been fading since the 1970s!
