Incorrectly heard lyrics are called "mondegreens." The word originates with journalist Sylvia Wright, who wrote a column in the 1950s in which she recounted hearing the Scottish folksong The Bonny Earl of Morray. Wright misheard the lyric "Oh, they have slain the Earl o' Morray and laid him on the green" and thought it was "Oh, they have slain the Earl o' Morray and Lady Mondegreen."
