Narrative:

While performing preflight duties the captain and myself were in the cockpit when the whole plane shook abnormally during the boarding process. I looked out my side window and witnessed a deice truck under our right wing. The deicer backed out from under the wing causing more shuddering of the aircraft. I called company ops to let them know what happened then went down on the ramp to see the damage. Not sure why; we did not even call for deicing.
