The line comes from Paul Thomas Anderson's 2007 film There Will Be Blood, spoken by oilman Daniel Plainview, played by Daniel Day-Lewis, during his final confrontation with preacher Eli Sunday. Plainview explains oil drainage by comparing neighbouring wells to straws in one milkshake, then boasts that he drinks the other man's share. The scene circulated widely as a clip and a quote after the film's release, and later spread through YouTube edits, reaction videos and TikTok, where its mix of menace and absurdity made it an easy shorthand for greedy, winner-takes-all behaviour.
