After pushback; we noticed restricted articles in the forward cargo. None of us had seen a NOTOC; so I called Ops. Turns out; it was given to the Relief Pilot who was new on the B777. On top was our water service slip; so he thought it was that. When I looked at the NOTOC it said Flammable Liquids. Under the UN number was XXXX. External Combustion Engine. What concerned us was Flammable Liquids. I called Dispatch and got Load Control involved but the Flammable Liquid part was never resolved as to what and how much it was. We returned to the gate and had the items removed. This event occurred because the NOTOC was very vague in its description. It did not have the shippers name; only and international emergency number. Yet in the FOM; [it] states that Flammable Liquids are permissible; but that's it. It does not describe what Flammable Liquids constitute or how much you can carry. FOM Prefight Dangerous goods limitations states; 'the Cargo Department is responsible for ensuring cargo dangerous good weight; quantity and distribution limits are complied with. Nowhere on the NOTOC was the flammable liquids quantity or weight was listed. Shippers of Dangerous goods need to have more detailed description in cases like this.
B777-300 Captain reported Flammable Liquids loaded in cargo for transport with incomplete information on required documents.
