enjō

Provenance — where it came from

Enjō is plain Japanese. A house, a factory, a ship: when it burns, the newspapers write 炎上. The word carries no internet in it at all.

In the 2000s it was handed a second job. Message boards and personal blogs had made it possible for one careless sentence to reach thousands of strangers in an afternoon, and those strangers could answer all at once — hundreds of comments, faster than anyone could read them, let alone reply. The clearest early cases date from the mid-2000s, when a few blog posts by public figures collapsed under exactly that weight. It is said the transfer came by way of baseball, where a pitcher who gives up runs in a sudden rush is also described as enjō. The account is not confirmed, but the shape fits: a thing that was fine a minute ago, and is not now.

The grammar is worth noticing. In English, flaming is something people do — the verb belongs to the attackers. Enjō suru belongs to the target. The post burns. The company burns. No one strikes the match, because in the metaphor there is no match; there is only the fire and the thing inside it. Once the word was in place, the rest of the vocabulary built itself out of the same material: 燃料投下 (nenryō tōka), dropping fuel, for a reply that makes things worse; 延焼 (enshō), the spread to the next building, for when the writer’s employer or family is pulled in; 鎮火 (chinka), extinguishing, for the day it stops. There is even 炎上商法 (enjō shōhō) — setting the fire on purpose, because attention is attention.

The same machinery, in better weather, is バズる (bazuru, № 030): a post spreading far past its author, to applause. One mechanism, two names, and the language kept both.

By the 2010s the word had spread well beyond the internet. Television news used it without explanation. Companies wrote it into their manuals and hired firms to put fires out. A metaphor borrowed from house fires had become the standard name for one of the ordinary risks of speaking in public.
