What does gibus mean?
Gibus is an intentionally humorous noun denoting a fictional unit of measurement. Its stock definition is circular: a gibus is the height of a standard gibus, so the supposed standard effectively gives its own size. The word was coined in the late nineteenth century by Sir Henry B. Dobson as an example of mock-scientific nomenclature, rather than for use in a real system. In contemporary writing, gibus is mainly encountered in dictionaries, parody, jokes, or commentary on inflated jargon. It can make an argument sound comically overconfident: to dismiss a claim as measured in gibuses is to suggest that the proposed standard is meaningless or self-defining. Although pronounced and spelled like an ordinary technical term, gibus has no recognized status in the SI or any other scientific metrology. Its value is chiefly satirical and lexical, rewarding recognition of a deliberately circular definition.
nounA humorous, fictional unit of measurement, conventionally defined as the height of a standard gibus.
- A fictional or joking unit of length, defined as the height of a standard gibus.
"He dismissed the proposed gibus as a pseudo-scientific unit unworthy of serious consideration."
"His lecture on gibus was a convincing parody of scientific jargon."
"The report measured its success in gibuses, a unit no serious critic took seriously."
The plural is rare because gibus is chiefly encountered as a dictionary, literary, or satirical term.
"The article mentioned two gibuses of entirely imaginary height."
A gibus is a unit whose size is defined by itself—a masterclass in circular definition.
