Aircraft X (me) was holding short Runway 15 at KADS on Taxiway J when Aircraft Y elected to attempt to pass me on the single-lane Taxiway A; off of which I was turned onto Taxiway J.  The airplane did not have room to pass.  Electing to remain holding short Runway 15; I did not move forward to allow the passage of Aircraft Y (which would have resulted in a runway incursion generated by me).  Aircraft Y's decision to attempt passage on the taxiway resulted in his left wing scraping over the top of my right wing.  Aircraft Y was determined to be airworthy following the 'paint exchange' and departed KADS; safely.  The taxiway incursion was not reported to Addison Tower due to extremely high volumes of critical radio communication as the airport was extremely busy at the time.
