Human Factors; Procedure
After landing on 27L at ORD; cleared the runway at A1 and joined Bravo. The unspoken rule in ORD is 'don't stop moving' unless Ground tells you to. I proceeded down B expecting to be cleared to [the] gate or to the holding block if not available. Ground Control was congested and I was approaching A3 with no contact yet. An Airbus was holding short of B on the west side of B; slightly beyond the hold bars; as he was probably told to hold short of B with late notice.(This will happen often when an aircraft clears at A1 such as we did). Proceeding past the Airbus required me to proceed very slowly to insure wingtip clearance with his nose. At this point ORD ground finally made contact (with a quip about me plowing right through); asked our gate; and cleared us to [that gate]. Ground did not seem to have a problem with my actions. Right after we acknowledged instructions to the gate; an unidentified comment came across 'he nearly clipped us'. I have to assume this was [the] Airbus referring to my passing. We proceeded past [the] Airbus with complete caution and had no doubt we were clear of his aircraft as we passed. This event only caused me concern due to the comment by [the] Airbus. I do not believe I deviated from 'normal' ORD procedures and did not receive any feedback from ORD ground.

B737 flight crew reported that; while taxiing to the gate at ORD; the pilot of another aircraft  expressed concern about the perceived insufficient separation.
