Every language if full of clichés, and American English is no exception. As a matter of fact, in its contemporary state as driven by media gobbledygook, American English ranks as the most cliché-ridden language known to Y-H-B.
Some speakers seem to thrive on clichés and other such linguistic detritus. For instance, there is one person, whose speech I regularly overhear, who cannot respond to any interlocutor’s utterances without saying “Wow!” It seems not to matter that there is nothing remarkable in the utterance to which this person is responding with this vocable. Perhaps this sort of speech trait is to be attributed to a species of anosognosia, however non-clinical.
