Literal translation
to make the snout
Meaning
to sulk
Explanation
To sulk, the equivalent of the standard French faire la tête. Mourre means an animal's muzzle, but the word is commonly used in Provençal for a person's face, with no negative connotation. Since bad moods show on the face, faire lou mourre took hold as the phrase. The extent of the sulking is sometimes measured with faire un mourre de tres pan, the pan being a traditional 24-centimeter unit, or with the rarer variant faire lei brigo, the jaws.
