This word comes from a combination of /dev/nul
. The root word 'nul' is considered to translate to 'void' or 'absence'. 'Flux' can have different meanings depending on context but in this definition it most closely resembles 'change' or 'modification'. Therefore the combined meaning of the word 'nulflux' is: The absence or void of change; static.
This term was first used by Steven A. Hammock to describe the unfaltering hate he harbors for his stepfather.
"The hatred inside me is in a state of constant nulflux. It never changes."
