hacne
A row of angry pimples across your forehead from wearing a hard hat all day and sweating like a pig in a sauna.
Construction worker’s forehead looks like it got hit by a pimple grenade.
That hard hat has been on his head since 7 AM. Now his forehead is a pimple battlefield.
He wore that hat in 90-degree heat. His forehead looks like it's melting.
