Literal translation
to make one turn faster than two
Meaning
to be slow, sluggish
Explanation
To be slow, sluggish, not very sharp. The phrase implies that an efficient worker would get two rounds done rather than one, a classic hyperbolic image. But in Provençal it mainly turns on a pun: pu lèu, faster, sounds exactly like pulèu, rather, so a pu lèu fa un tour que dous also reads as he rather did one round than two, someone choosing to do the least possible. A related, very vivid saying describes someone dragging their feet to work: quand il y va on dirait qu'il en vient, when he goes there you'd think he was coming from it.
