the willies

今日の単語 "willies" は前にも取り上げていますがまた忘れたので再度取り上げます。　次ぎの文はリーダーズダイジェスト9月号にあった記事からです。（何の記事であったかはメモしなかったので不明）
The idea of having another human, even a medical human, becoming deeply involved in what is technically known as your "behindular zone" gives you the creeping willies.

ダメ押しに語源辞典も見ます。
Online Etymology Dictionary: 1896, "spell of nervousness," perhaps from the woollies, a dialectal term for "nervous uneasiness," probably in reference to the itchiness of wool garments.
"the willies" の語源が "woollies"、"itchiness of wool garments" から来ているというのを覚えれば真偽はともかくとして "the willies" の意味は覚えられそうです。
ところでＲＤの記事に "behindular zone" の "behindular" は辞書に出ていない単語ですが、"behind" + "ular" の合成語でしょう。 "ular" を辞書で引くと次ぎの様な説明があります。
・Dictionary.com: suff. Of, relating to, or resembling: tubular.
・Mosby's Medical Dictionary:
1 combining form meaning "pertaining to" something specified: appendicular, molecular, pedicular.
2 combining form meaning "resembling" something specified: circular, globular, tubular.
"ular" はcellular-phoneにも使われている接尾辞ですね。
