I reviewed some information in archives that is consistent with my thoughts.
A resistor or resistance is considered Ohmic if it has a linear IV plot. A proportional increase in amperage for a proportional increase in voltage.
Ohm's law doesnt break but if the resistance changes at a given applied voltage then it may not be ohmic or in other words it is nonlinear.
A light filament is a good example. So is a diode. Even a solenoid may not be ohmic while the core saturates. Inductors generally seem like they wouldnt be considered ohmic.
For me what is mainly relevant is whether bad connections caused by loose wires that should be bolted down, or by heavily corroded wiring (green green).
If those are Ohmic, a resistance check with an ohm meter can be semi useful.
Spark plug gaps that ionize and become conductive come to mind...
What types of things tend to be Ohmic and what types arent?
