Literal translation
to burst one's little lamb
Meaning
to work oneself to exhaustion
Explanation
Bédélet first means the little belly, hence the related expression to laugh oneself sick with a burst bédélet, comparable to laughing until one's embouligue bursts. But the word also means the rectum, from budèu, "gut". To si creba lou bedelet then means, bluntly, "to break one's ass", that is, to make great physical or intellectual efforts. These two forms, identical in shape but different in origin, are simple homonyms. On the coast, people also say to break one's maffre.
