the.com/craze

means An intense but short-lived enthusiasm that spreads through a group of people, usually fading as fast as it caught on.

from From Middle English 'crasen,' meaning to break or shatter, related to Old Norse roots for crushing. The sense shifted from physical cracking to mental cracking — a 'crazed' mind was one fractured by madness, and 'crazy' followed the same path. 'Craze' as a fad came later, in the 19th century, carrying that same whiff of mild derangement: a fever that cracks people's good sense, at least for a while.
