OK, here's another word that needs to be dumped. It is three words, really: improvised explosive device.
No. 1, give me a break. It has way more letters than what it means: roadside bomb.
No. 2, it gives unimaginative bozos an annoying way to talk about any policy they disagree with: "It's improvised, explosive and divisive!"
No. 3, it has that familiar ring of words that hide something, especially when the name is nicked to IED. "The IED went off" just doesn't quite put the same message across as "the bomb went off."
I'm sure there are other reasons, but I think I've found enough.
