A frivolous, faddish, or temporary enthusiast; someone who jumps from one trendy thing to another without real commitment.
From reduplication of fid- or from dialectal fiddle-faddling. This whimsical word emerged in 18th-century English to mock superficial trend-followers.
Fidfads have always existed—people who adopt fashions, hobbies, or beliefs just to seem interesting, then abandon them months later. The word itself sounds silly because the behavior is silly.
