1. fashion => fad, faddish.
fad 一时的狂热

可能来自拉丁语fatuus, 无味的,愚笨的,词源同fatuous. 原义为小的兴趣爱好,癖好。后用来指没主见,盲目跟风,一时狂热。

fad (n.)
1834, "hobby, pet project" (adjective faddy is from 1824), of uncertain origin. Perhaps shortened from fiddle-faddle. Or perhaps from French fadaise "trifle, nonsense," which is ultimately from Latin fatuus "stupid." From 1881 as "fashion, craze," or as Century Dictionary has it, "trivial fancy adopted and pursued for a time with irrational zeal."
