"Dodoes" is a word that refers to the extinct, clumsy flightless bird native to Mauritius. In modern times, this word has taken on a more figurative meaning to describe someone who is foolish or slow-witted. There are many synonyms available that can be used to describe such a person without using the term "dodoes". Some common ones include: dim-witted, simple-minded, slow, dense, air-headed, gullible, naive, ditzy, dull, and clueless. All of these words can be used to describe someone who is not very perceptive or quick-witted, without resorting to using a term that specifically refers to a prehistoric bird.
