The occurance when an overweight person, generally a female chav by nature, wears a small and revealing top or jacket, exposing their large belly to others.
This chavbelly phononemon is seen as an offense in many places across the UK, particularly the Yardley area of Birmingham, where it occurs most.
His name is Chadwick and he is a little queer who asks to get into parties yet no one wants him there. Constantly describes his mother’s death to get out of situations and to get “poon”. A Chadballs is essentially a loser and a person who will do anything to fit in. If you see someone like this simply call them “Chadballs” and politely tel them to fuck off.
