Narrative:
At cruise; clear; smooth. We were assisting a passenger in getting refreshments from the galley area just behind the pilot; when we began to sense a 'burble' that rapidly increased in intensity to near moderate turbulence; rolling the aircraft to perhaps a 45-degree right bank; causing the autopilot to disconnect. The roll caused the aircraft to descend; until I realized what was happening and took manual control; leveling the wings; climbing back to altitude and returning to track. We then contacted center and advised them of the turbulence; upset; and deviation from altitude and track. The information regarding the location of the disturbed air was passed along to other aircraft in the area.
