Cockalorum sounds like a spell from a Harry Potter book, but it is actually a word that means ‘a small man with narcissism or a self-important man’. This word was used quite often in England during the 18th century. This word fell out of popularity quickly, although you can still hear people using the term when talking about politicians or celebrities in the bars – according to a few friends of mine. XD
So, how would you using cockalorum in a sentence?
That man is a cockalorum if ever I met one.
If he keeps talking like that they may think him a cockalorum.
