avoir du front tout le tour de la tête

To have outrageous nerve

Someone with front tout le tour de la tête has so much nerve it might as well wrap right around their skull, the superlative version of plain 'avoir du front'.

Il a demandé une augmentation le jour même où il est arrivé en retard, il a du front tout le tour de la tête.

He asked for a raise the same day he showed up late. The nerve of him.

Origin uncertain. It reads as the exaggerated cousin of the plainer 'avoir du front' (to have some front, meaning some cheek), with the front stretching all the way round the head for full effect.
