1 'A catch phrase is a phrase that has caught on, and pleases the populace.' I'll go along with that, provided these substitutions be accepted: 'saying' for 'phrase'; and 'public' for the tendentious 'populace.'. ( 2 Eric Partridge, A Dictionary of Catch Phrases. 3  Routledge, 1986).
Idiom of âcatch-phraseâ. A catch-phrase tends to have a more ephemeral resonance than an idiom. It is a fixed phrase which has gained media popularity and thus spreads into the wider culture. It is often based on a memorable jingle, slogan, stock response or quotation from an advertiser, a politician or an entertainer. Sometimes a catch-phrase is a complete sentence. Often it attains a range of resonances far beyond the intentions of its originator.
