Semper Fi is a Latin phrase that means “always faithful.” It is used by the United States Marine Corps (USMC) as a motto to demonstrate their commitment to honor, courage, and commitment. The phrase has been adopted by other branches of the military, as well as the general public. As such, the phrase is often used in tattoo designs, usually by people who have served in the military or have a strong connection to the military. For women, the Semper Fi tattoos often take on a more feminine look, with a variety of designs, colors, and locations.
