Meaning
An informal, blunt command to stop talking immediately.
It’s usually said half-jokingly among friends or family rather than as a genuinely hostile order, though tone and context can sharpen it considerably.
Origin
The phrase draws directly on the mechanical action of a zipper fastener, which became a common everyday closure on clothing and bags in the early-to-mid 20th century after Gideon Sundback’s 1913 improved design made zippers cheap and reliable enough for mass use. Once zippers were part of daily life, “zip it” and the related “zip your lip” naturally extended the image of pulling a zipper shut to closing one’s mouth, giving English a vivid, physical replacement for the older, blunter “shut up.”
Examples
