Hi Yaelle,
I just listened at the link you posted. I think the only poster there (as of now) has it correct: “F***ing CONES.” Give it another listen? I believe that is exactly what he’s saying.
Best Regards,

If there is context for the word cones, it could be that. For instance, if there were cones blocking the road where he was driving. Absolutely, it could be cones.
