The term 'Typical Bellybutton Type' is referring to the shape of a person's navel. The most common type is an 'innie, ' which is a navel that is indented or sunken inwards. This is in contrast to an 'outie, ' which is a navel that protrudes outward. An innie is typically formed when the umbilical cord is cut close to the baby's abdomen, leaving a small scar that causes the navel to be indented.
