What does cruncher mean?
A cruncher is a person or device that crushes or grinds with a crunching noise, but in contemporary English the word survives almost entirely in one vivid figurative use: the number cruncher. In this sense a cruncher is any computer, processor, or person engaged in heavy-duty calculation — analysing statistics, running financial models, or processing vast datasets. Calling a machine a number cruncher is affectionate and slightly playful, evoking an image of silicon teeth grinding relentlessly through figures; applied to a person, it describes someone whose strength lies in quantitative analysis rather than creative flair. The word derives from the verb crunch, itself imitative in origin, suggesting the grinding sound of hard work. Outside its computational niche, the literal sense — someone munching loudly on crisps, for instance — still appears in casual speech. Cruncher is informal in register and best avoided in formal technical writing, where terms like processor or analytical engine are preferred.
A computer, processor, or program that performs intensive numerical calculation; by extension, a person skilled in such work.
"Hired as the firm's chief number cruncher, she quickly uncovered the error in the quarterly accounts."
Nearly always appears in the phrase 'number cruncher'; informal but widely understood.
A person or thing that crushes or grinds with a crunching sound.
"The garden shredder proved to be a merciless cruncher of fallen branches."
Literal, colloquial sense; much rarer than the computing sense.
Regular plural; typically used of machines or people in the computing sense.
"Modern laptops are surprisingly capable crunchers of spreadsheet data."
Before it described supercomputers chewing through data, a cruncher was just someone making a racket eating crisps.

Etymology of cruncher
Cruncher is formed straightforwardly from the verb crunch plus the agentive suffix -er, a pattern common in English for naming both people who do something and machines that do it. Crunch itself dates back to at least the early nineteenth century and is imitative in origin — an echoic word mimicking the sound of noisy biting or grinding, akin to scrunch and crackle. The figurative computing sense, especially in 'number cruncher', arose in mid-twentieth-century American usage alongside the rise of electronic computation, when early machines were imagined as voraciously 'chewing' through figures.
How cruncher is actually used
Almost always used informally, and overwhelmingly encountered within the fixed phrase 'number cruncher', referring to computers, programs, or people skilled at handling large volumes of calculation. The literal sense (someone or something that makes a crunching noise when biting or crushing) exists but is comparatively rare and colloquial.
Easily confused with cruncher
Not applicable — the confusion is between senses of the same word: the literal sense (someone or something that crunches) and the computing sense (a machine that processes data).
