This gets even more fun when several communities discover the same thing independently, and each comes up with a different name for it.
My favorite is the idea of "let's expand functions over a set of Gaussians". That is variously known as a Gabor wavelet frame, a coherent state basis [sic], an Gaussian wave packet expansion, and no doubt some others I haven't found. Worse still, the people who use each term don't know about any of the work down by people who use the other terms.
