Flag and History
Lightninggender, as well as the subsets lightningfem, lightningmasc, and lightningneu, were coined by user ReversedServers on Scratch on June 3rd, 2021. The flags were made on the same day. The subsets lightningandrogy and lightningxeno were later coined by the same user, and their flags were created.

Etymology
The prefix lightning- comes from the English word lightning, which is a biological phenomenon that happens in small flashes. The suffix -gender has an obvious meaning, though combined with the prefix it means "flashing gender" which is similar to flashgender, alternate name for the term.
