squib

Squib is a term with several distinct meanings in English. In literature and publishing, a squib denotes a short, witty, or pointed piece of writing, often a brief topical note, sketch, or humorous item in a magazine or newspaper. The term is also used for a brief satirical piece that may stand alone or accompany a larger article.

In pyrotechnics and special effects, a squib is a small explosive device or charge used to create a localized effect or to ignite a larger charge. In film and theater, squibs are commonly used to simulate gunshots or to produce controlled explosions; safety regulations govern their design and handling.

In firearms and ballistics, a squib can refer to a cartridge that fails to generate enough pressure to propel the bullet, leaving a partial burn or a stuck bullet—also called a squib load. Such incidents are hazardous, especially with subsequent firing.

In the fictional domain, particularly in J.K. Rowling's Wizarding World, a squib is a non-magical person born to magical parents, one who lacks magical abilities despite its lineage.

The term's meaning depends on context, ranging from a brisk literary note to a small explosive device, a misfired cartridge, or a person lacking magical power.
