Literal translation
to look like the ravi figure in the nativity scene
Meaning
to stand with arms raised, like the ravi figurine
Explanation
The ravi is one of the traditional figures of the Provençal Nativity scene, always shown with arms raised in surprise and veneration, often appearing at a window. Supposedly the village idiot, he is nonetheless touched by the grace of the event, which makes him one of the most endearing santons. The expression describes someone with arms raised in the air, or looking foolish, in a mocking tone that always carries affection. People sometimes strike the pose themselves to mimic great joy when visitors arrive.
