Goose or Chilly Bumps or Pimples?

I've heard many people use the term "goose bumps"; in my family, they were "goose pimples," but I don't know if this was peculiar to us, or if others also use it.

My wife's family's saying for this was "Chilly bumps."

Are there others? Is one considered the "most correct"?

The google (books and web) says that "goose bumps" (also one word, "goosebumps") is by far the more favored term over "goose pimples" or "goose flesh." The technical terms for this phenomenon is cutis anserina, horripilation, or piloerection.

The google finds over 750K uses of "goose bumps" and only 124 of "chilly bumps." I didn't look closely at the latter results, but I bet most of them are from your wife's family.

The Ngram chart for "goose bumps" (blue line) versus "goosebumps" (red line) versus "goose pimples" (green line) versus "goosepimples" (yellow line) versus "goose flesh" (light blue line) versus "gooseflesh" (purple line) versus "chilly bumps" (no line because there were too few matches) for the period 1840–2008 is interesting:

The most striking development shown in the chart is the precipitous rise of "goose bumps" from near zero to world domination between 1960 and 2005. From 1900 to 1930, "goose flesh"/"goose-flesh"/"gooseflesh" predominated; and from 1940 until the late 1970s, "goose pimples" ran a reasonably strong second. But the recent ascent of "goose bumps"/"goosebumps" makes these other trends look relatively minor.

William Safire, "On Language: That Icy Tingle," in the New York Times (November 7, 1982) quotes a representative of the Dictionary of American Regional English as offering a very different hierarchy of usage:

"Goosepimples is by far the most common response," reports Joan Hall, associate editor of DARE, the soon-to-be-published Dictionary of American Regional English, "with goosebumps being offered about half as frequently. Gooseflesh comes in a distant third." No geographic distinction shows itself, but older people tend to say gooseflesh, while younger people lean toward goosebumps, ...

But Ngram shows"goose bumps" and "gooseflesh" in a virtual tie for the most common form in works published in 1982, with "goose pimples" a distant third, only slightly ahead of "goosebumps."

As for alternative names for the condition, Safire offers a baker's dozen of options, presumably culled from regional dictionary research:

Lexicographic Irregulars across the country are going to read this and say, "Why, that city boy is talkin' about chicken skin. Or duck bumps, thrill bumps, chilly bumps, turkey bumps. Or he's fixin' to say he's about to sprout feathers. Or he's got prickles, pins and needles, French knots, eggerbumps, ash spots, white measles or chill bugs."
