Narrative:

Taxiing to gate. I was unfamiliar with bos (I was on IOE) and didn't realize that the captain's speed was inconsistent with a 'hold short' instruction. Ground queried if we were going to hold short. Captain stopped short of active runway, however an air carrier MD80 heard the confusion and elected to abort their takeoff roll.
