A short, memorable phrase or saying that someone is known for repeating, often used in advertising or comedy.
Compound of 'catch' (from Old English 'kecchen') and 'phrase' (from Late Latin 'phrasis' meaning 'speech'). The 'catch' element suggests something memorable enough to stick with audiences, while 'phrase' is a sequence of words. Popularized in the 20th century with radio and television advertising.
