Mente de Pollo
Used to describe a scatterbrained person who forgets things very easily (literally chicken mind, referring to the idea that birds have tiny brains and poor memories).
Yesterday I told Maria that I would wait for her at the mall at 3:00 today. Well, I waited and waited, I called her at 4:00 and she had forgotten, so I told her, oh Maria, you really are Mente de Pollo.
