What does cribber mean?
A cribber is someone who copies or plagiarizes, particularly a student who cheats by passing off another's work as their own. The word carries a dismissive, mildly contemptuous tone and appears most often in informal or older British school and university contexts, though it remains understood more widely. A second, quite different sense belongs to the world of horses: a cribber is a horse that has acquired the habit known as cribbing or crib-biting, in which it seizes a fence rail or stall edge with its teeth, arches its neck, and swallows air—a stable vice that can wear down teeth and frustrate owners. Both senses derive from the older verb "to crib": to confine or enclose, and later, in student slang, to copy illicitly. Whether applied to an exam-hall offender or a windsucking gelding, calling someone a cribber labels them as an habitual, disreputable practitioner of the vice.
A person who plagiarizes or cheats by copying others' work, especially in examinations.
"He was expelled not for failing, but for being an unrepentant cribber."
A horse that has the habit of cribbing, seizing solid objects with its teeth and swallowing air.
"A confirmed cribber will wear down its incisors on any available rail."
This sense is used mainly by those involved in horse care and management.
Standard plural; applies to both the human and equine senses.
"The invigilators caught two cribbers during the morning session."
In stables, a "cribber" isn't cheating on a test—it's a horse that grips the stall door with its teeth and gulps air, one of the most notorious habits an owner can face.

Etymology of cribber
"Cribber" is formed simply from the verb "crib" plus the agentive suffix "-er." The underlying noun "crib" goes back to Old English "cribb" or "crybb," meaning a manger or enclosed bed, and is cognate with Dutch "krib(be)" and German "Krippe," all from a common West Germanic root; the word is thus related to the German "Krippen" found in "Weihnachtskrippe" (Christmas nativity scene). From the literal sense of an enclosed space came figurative uses—to crib someone up—and by the seventeenth century "crib" had also come to mean a pilfered or purloined thing, which led to the student sense of copied work and hence to "cribber" as the person who copies. The equine sense arose separately from the practice of describing a horse that grips its crib or manger as one that "cribs."
How cribber is actually used
The academic sense is somewhat informal and dated, more common in British usage and in older school and university writing; modern contexts tend to use "plagiarist" instead. The equine sense is technical vocabulary within horse care and breeding circles.
