The line comes from Monty Python and the Holy Grail, the 1975 British comedy film written and performed by the Monty Python troupe. In the film the understated cheer follows grim news delivered as if it were a triumph, a gag that became one of the movie's most quoted moments. Clips and quotes spread through fan communities, forums and later meme edits, where the phrase is now shorthand for forced enthusiasm, reluctant relief and celebrations that feel far smaller than promised.
