The name given to any hanging piece of biological matter that resembles the post-pubescent testes or chicken's wattle
and wobbles uncontrollably and hilariously.
Found mainly in the neck region but not confined to it and most prevalent in elderly persons who may have undergone substantial weight loss.

Graham: This meal is lovely thanks Gethin. Haha, look at that man over there. He's got a gooch and it wobbles as he eats!
Gooches (or Geech as they are often termed in plural) are characterised by a jelly-like wobble. If they don't - it's more than likely a Gooch wannabee!
