So I first saw this GIF a few years back and ended up seeing it so much that I got curious. When no one could give me sauce, my curiosity intensified.
And this evening.
I finally found sauce.
It is from a french movie called ‘Marquis’ which explores themes from the life and writings of Marquis de Sade through a story about absolutely terrifying anthropomorphised animals, one of which is a dog imprisoned in the Bastille, who has conversations with his penis (named ‘Colin’) about his pornographic writings and his lust for debauchery. Memorable scenes include a cow-woman getting raped by a homosexual rat-man (=he mistakes her udders for many penises and wanks/milks them until they bleed) and that same rat-man bending over hoping to receive anal sex from the dog-man, who is told by his penis/Colin to instead shove a lobster lubricated with mayonnaise into the rat-man’s ass. All this is accompanied by nightmarish accordion music.
