PA-28-181 instructor pilot reported a near miss with another aircraft during taxi while stopped in a non-movement area prior to a taxiway; on a training flight. The other aircraft maneuvered past with little to no clearance or coordination between aircraft; there was no damage and the instructor reported the hazard.

Narrative

We were in the nonmovement side of Taxiway 1 at ZZZ at 2 waiting for traffic taxiing to the ramp eastbound from Runway XX on 1. We were on the centerline stripe; stopped; and expected the C172 to pass 2 and enter the ramp via 3 as in normal operations. The aircraft stopped and started to turn; as in attempting to pass us. My student reacted by moving forward slightly and off-setting; which I stopped since there was no way to make room for the aircraft to pass. I asked Ground on the radio for Ground to direct the C172 to proceed east to 3 in order to deconflict us; while motioning via hand for them to continue East. As the C172 proceeded to move in our direction; I open my aircraft door and gestured outside the aircraft for them to stop and proceed east. They continued to try and pass along my aircraft and a parked C172 to our east. I radioed Ground that I felt this was unsafe; and that our wings were going to overlap (his a high wing; my low wing). The C172 proceeded to pass us with certainly less than 1' of clearance; if not an actual wing overlap. When I asked how to report this event to Ground Control; they claimed that it was on the nonmovement side of the ramp; and that a report would be the most appropriate reporting tool. After this exchange with Ground; the pilot of the other aircraft said; on Ground Control frequency no less; 'don't be an asshole'. This is CLEARLY a hazardous attitude; with no realization of how serious and poorly this situation could have resulted. I felt that he operated his aircraft recklessly and without any regard to my safety; and then is belligerent when called out. This type of hazardous attitude is exactly what leads to mishaps. After this event and aggressive radio exchange; he realized he was at the wrong FBO; and asked for what ended up being a progressive to a different FBO. Clearly this pilot was not familiar with ZZZ; and there is a high degree of likelihood that an airfield diagram was not being used.
