The line comes from Paul Thomas Anderson's There Will Be Blood (2007), shouted by Daniel Day-Lewis as oilman Daniel Plainview during the film's infamous baptism scene, where he confesses to having abandoned his son H.W.

Online it circulates as a reaction clip for exaggerated guilt and betrayal, sitting comfortably alongside other anguished movie screams like Darth Vader's famous outburst.
