The term 'cantankerous sort' can be broken down into four words: CODGER, OGRE, CUSS, and CRAB. A CODGER is an old person, usually one who is grumpy or cantankerous. An OGRE is a mythical creature that is often portrayed as a large, mean, and aggressive monster. A CUSS is a swear word or an insult. Finally, a CRAB is a crustacean that is known for its bad temper and irritability. All of these words together describe someone who is difficult to deal with and has a bad attitude.
