A pet phrase is a term or expression that is frequently used by someone, often to the point of becoming cliched or annoying. There are many synonyms for this term, including catchphrase, cliche, idiom, mantra, saying, slogan, catchword, buzzword, cliche, maxim, platitude, catchline, trademark and signature phrase. Although these phrases are often used by different people to describe different things, they all refer to expressions that are overused or have lost their original meaning through repetition. While a pet phrase can be a useful tool for communication, it is important to use it sparingly and to always strive for fresh, original language in writing and speaking.
