The line comes from Bad Santa, the 2003 dark comedy starring Billy Bob Thornton as Willie, a miserable con man working as a mall Santa. His exhausted, profane outbursts became the film's signature humor, and short clips of his rants later circulated as reaction audio on forums, Vine era edits, and meme soundboards. This quote endured because it captures instant disbelief in under two seconds, making it easy to reuse for lies, scams, and absurd reveals without needing any visual context from the movie itself.
