Have you ever listened to someone who uses a particular phrase so often that you expect to hear it whenever you speak with that person? Are there certain phrases that you use often in everyday conversation? Think of the “trendy” phrases that become (for me anyway) like fingernails on a chalkboard; for example, push the envelope, I hear you, piece of cake, I could care less, my bad, just sayin’ (and a new one that I heard recently – totally salinda meaning peacefulness, or a peaceful state of mind).
Interestingly, every language has well-used colloquialisms and idiomatic expressions; for example, in Italian in bocca al lupo literally means "into the wolf's mouth" but, rather like the strange English expression "break a leg," this phrase is used in Italy to wish someone good luck.
Choose a phrase (not a cliché but a common idiomatic expression) and write a poem "around" that phrase. Alternatively, you might try using that phrase as much as possible within your poem. Turn the expression over and around, spin it, repeat it, extend it, give it new meanings, mock it, praise it, see how far you can stretch it. You might even consider using the phrase as a metaphor.
Begin by making a list of expressions that you or friends use often, and then choose one for your poem. Another idea is to use several phrases throughout your poem, or perhaps even compose an entire poem of “phrase plays.” Try taking a humorous approach – have fun with this!
