The phrase comes from the traditional cumulative children’s song commonly known as “There Was an Old Lady Who Swallowed a Fly.” Each verse introduces another animal and repeats earlier events, with the bird verse using “absurd” as its comic rhyme. The song has appeared in recordings, books, classrooms, and children’s performances for generations. Short excerpts remain useful online because the familiar rhyme communicates escalating nonsense immediately, even when separated from the complete song. It is often applied to surreal edits, questionable choices, and bird-related jokes.
