Bad Thing

[from the 1930 Sellar & Yeatman parody `1066 And All That'] n. Something that can't possibly result in improvement of the subject. This term is always capitalized, as in "Replacing all of the 9600-baud modems with bicycle couriers would be a Bad Thing". Oppose Good Thing. British correspondents confirm that Bad Thing and Good Thing (and prob. therefore {Right Thing} and Wrong Thing) come from the book referenced in the etymology, which discusses rulers who were Good Kings but Bad Things. This has apparently created a mainstream idiom on the British side of the pond.
