What Does Plug and Pray Mean?

Plug and pray refers to user skepticism about the functionality of a new technology or device. The term is a variation on the term “plug and play,” which is used to promote wireless or other devices that are supposed to be easy to install in a larger IT setup. By contrast, the term plug and pray indicates that the user doesn’t really know if the technology will work; he or she will simply plug in the hardware and hope for the best.

Techopedia Explains Plug and Pray

Different kinds of operating systems and software have been described as being plug and pray by those who doubted that the products would work the way they were supposed to. The same holds true for wireless mice or other peripherals. With limited electronic drivers and software components, these devices might be simple to install, but may not work as they were intended to.
