What eyebrow should boys get pierced if they have an earring in the left?

It is generally not recommended to pierce both eyebrows if you already have an earring in one ear. Having piercings on both sides of the face can create an unbalanced look and can be considered too excessive. If you wish to get an additional piercing, it would be more advisable to choose a different location, such as the opposite ear or a nostril, to maintain a sense of balance and harmony in your facial appearance.
