The line comes from Home Alone, released in 1990, where Kevin McCallister watches a fictional gangster film called Angels with Filthy Souls and later borrows its tough-guy dialogue. In that black-and-white scene, the mobster Johnny delivers the Christmas insult as a mock farewell, and Kevin reuses the attitude to scare off intruders. The quote escaped the film to become a seasonal catchphrase, printed on cards and jumpers and quoted in holiday videos every December. Its appeal is the contrast between warm Christmas wishes and a deliberately rude gangster send-off.
