noun. A slight break in the line of a beard or moustache on one side of a man's face. Usually the person is trying to grow facial hair where the component parts, such as sideburns, moustache and beard, are intended to join, creating a seamless facial hair effect. A bagilhole is a bald patch of skin which interrupts the line of said facial hair.
George, your bagilhole is showing.
