The practice or tendency to repeat or imitate words, sounds, or ideas that others have expressed.
From 'echo' + '-ism' (a practice, tendency, or system). This term developed in psychology and linguistics to describe echo-like behavior as a systematic characteristic.
Echoism is why earworms happen—once you hear a catchy phrase or melody, your brain's echo systems lock onto it and won't let go, essentially giving you a biological jukebox stuck on repeat.
