The corna (Italian for horns, also mano cornuta) is a gesture with a vulgar meaning in Mediterranean countries. Its origins can be traced to Ancient Greece. It is realized by stretching the index and little fingers while holding the middle and ring fingers down with the thumb.
The same gesture is used for warding off bad luck or the evil eye. It is also used as a reference to Satan and Satanism, at least since the 1960s, and has a variety of meanings in heavy metal, where it is also known as devil horns, goat horns, throwing the goat, evil fingers, Pommesgabel, mano cornuto or just the horns.
The same gesture is known as Rock on in some U.S. rock music subcultures, and Hook 'em Horns when used by supporters of The University of Texas or its sports teams. In that context, it is used to approximate the shape of the horns of a Texas longhorn steer. Neither use is considered vulgar or satanistic.
Not to be confused is the sign for "I love you" in American Sign Language, which is made by also extending the thumb, or the shaka sign used in Hawaii, which is made by extending just the thumb and little finger.
