The line comes from Mr. Deeds, the 2002 comedy starring Adam Sandler as Longfellow Deeds, a small-town man who inherits a fortune and moves to New York. The film became a familiar cable and home-video comedy, and short spoken moments from it have continued to circulate as reaction clips and soundboard sounds. This brief complaint works apart from the plot because back pain is a universal, instantly understood feeling. Creators reuse it whenever an ordinary movement suddenly feels difficult, keeping the film's deadpan humour alive in short-form edits and memes.
