THE PLT INDICATED HE LOST CONTROL WHILE ATTEMPTING A ROLLING TAKEOFF AFTER TAXIING INTO POSITION ON THE RWY WITHOUT STOPPING. HE STATED HE NORMALLY STOPPED THE ACFT PRIOR TO APPLYING TAKEOFF POWER, BUT THIS TIME HE DID NOT. THE ACFT FIRST SWERVED TO THE RIGHT. THE PLT OVER COMPENSATED AND THE ACFT SWERVED BACK TO THE LEFT AND THEN BACK TO THE RIGHT OFF THE RWY.
