That's one way "nz flag in z80" makes sense to me. What else could it mean?

The Z80 part is right, but talking about a flag in the context of the Z80 instruction set it should be quite clear you mean a programming flag not a country flag

Never programmed on the z80, but a common flag in cpus is Zero or Not Zero (nz), that would be set when the result of an operation is not zero (or zero, depends on the architecture)

For example A = 0 (A being a generic register) would set Z to 1 and NZ to 0, and viceversa for A = 1

I believe it is nonzero ("jump if not zero" iirc)
