A backlash is a strong push-back from a lot of people against something that has just happened — a new law, a new rule at work, a film, a brand, a change in how people are told to live. It is not one person’s quiet dislike. It is a wave: anger, protest, boycotts, sharp talk in the news. You hear it most about and society: a policy “sparks a backlash”; a public person “faces a backlash.” The feeling underneath is that the change went too far, or too fast, and now a crowd is striking back. It is a newspaper and meeting-room word, not playground talk, but it is not stiff or academic. Though actually, there is an older, more physical sense still used by engineers: in gears, backlash is the little leftover movement before the teeth bite — slack that “lashes” the other way. The people-meaning grew from that picture of a whip or a strike coming back at you. As a verb it is less common; most people still say there was a backlash, rather than “it backlashed.”

- In ...breakages from high speed and irregular pitch, ten out of the eleven wheels had spur segments moulded from patterns, instead of by machinery; and in three of the ten the teeth were cast upon the felks, and were twisted and drawn, as they generally are when cast in this way, by the contraction of the mass of metal of which they form a part.

- 1894 William Westall. Tinkler. Ludgate Illustrated Magazine. Vol VIII Thrutch factory was a queer old concern. It had been built piecemeal-here a bit and there a bit. There were a new end and an old end, the spinning-rooms in the one being light and lofty, in the other low. and gloomy. Looms were shoved in everywhere. There were a "long shop" with three hundred, a "top shop" with a hundred, a "back shop" with fifty-three, and a "little shop" with fifteen. Never was its equal for gearing. Shafts were everywhere inside and out, overground and underground, climbing snake-like up the walls, and boring into the roofs; spurwheels, great and small, whirled, clashed and "backlashed" all over the place.
- Just as it began to get dusk and the shadows from the trees deepening the twilight that had already spread over the lake, giving a peculiarly lonesome effect that water always has upon the approach of night, Uncle succeeded in getting out the longest cast he had yet made — about seventy-five feet. Unfortunately, or perhaps I should say fortunately, his reel over-ran and backlashed for him. Patiently he set about untangling his line; I resting the oars and holding the boat stationary.
