fall off the turnip truck

Be absurdly gullible

To fall off the turnip truck is to arrive somewhere naive and unsophisticated, like a rural rube who literally tumbled from a farm vehicle.

Almost always used in the negative: I didn't just fall off the turnip truck—meaning I'm not as gullible or clueless as you seem to think.

The phrase implies someone is being underestimated or insulted.
