The term 'BOB or BEEHIVE' can refer to two different things. The first is a hairstyle, commonly known as a BOB cut or a BEEHIVE HAIRDO. This style is characterized by short hair that is cut straight around the head and often has bangs. The second is a type of COIF, which is a type of head covering worn by men in the Middle Ages. It was usually made of cloth and was shaped like a BEEHIVE. Both of these terms are used to describe a particular style or look.
