Rotary Potato 

Term used in street racing when the opposing vehicle is not great. Usually when someone calls your car a Rotary Potato it means your car sounds like there's a potato on the engine or muffler, OR your car is slow that it's not race-worthy.

rotary engine 

A type of internal combustion engine consisting of a triangular rotor which rotates in an eccentric orbital motion around a epitrochoid housing. Advantages of this design are a compact size, mechanical simplicity (a two rotor engine has only three moving parts), high potential power output proportional to size, lightweight, high-revving and extremely smooth in operation. Disadvantages include high rate of fuel and oil consumption, complex sealing arrangement and high seal count, weak torque, more fragile than a four-stroke piston engine, and lower long term reliability. Also known as a Wankel engine (pronounced 'Vonkel') after it's inventor, Dr Felix Wankel.

Mazda's RX-7 is probably the best example of a car employing a rotary engine.
