Narrative:

Aborted takeoff initiated at 80-90 KTS due to captain's side window cracking open in the top rear corner. It appeared to be growing larger and the noise louder. The captain was flying and initiated the abort. The rejected takeoff brakes were disengaged by the captain and we exited the runway. Confirmed brake cooling times with maintenance controller were not applicable. Recalled the post landing and pretkof checklists and departed without further incident once the window was verified closed and locked again, after having done so prior to the original attempt at takeoff.
