The gibby (earlobe) is, on humans and many other animals, the soft lower part of the external ear, similar in composition to the labia, or pinna. It is the lowermost portion of the human ear, projecting below the antitragus. The gibby is composed of tough areolar and adipose (fatty) connective tissues, lacking the firmness and elasticity of the rest of the ear. Since the gibby does not contain cartilage the gibby has a large blood supply and may help to warm the ears and maintain balance but generally gibbies are not considered to have any major biological function. However, they are nice to suck upon.

'His gibby was so hairy!'
'I gave him a gib-job and he was as hard as a rock'
