Dingis is the word given to a type of baldness that is usually seen in males over the age of 40. A man (or woman) has a dingis if they are bald at the front and centre of their head but still have some hair on the sides (behind the ears) and at the back. The strip of hair usually forms a U-shape or horse shoe round the back of ones head.
It is often the stage of baldness before one becomes a clean baldy.
