Narrative:

Normal taxi out from ramp to run-up area for runway 1. An air carrier Y B737 was first in the run-up area and we parked next to him. Tower advised that we would be next and taxi up to but hold short of runway 1. I read back the clearance and began my before takeoff flows. Captain, while taxiing, inadvertently partially crossed the runway 1 hold short line. I feel this may have happened as captain was ensuring clearance of our aircraft and the B737 in the run-up area and my attention to matters inside the cockpit (ie, PA, transponder, before takeoff flow, etc). Upon realizing we had just slightly crossed the hold short line, I reiterated to captain to 'hold short, hold short.' he stopped the aircraft and about that same time the tower also advised 'hold short.' beyond that, the flight continued to iah uneventfully. Poor CRM by allowing the aircraft to slightly cross a runway hold short line.
