The 'I'm So Stuffed With a Little Turkey' shirt parody originates from wholesome maternity apparel traditionally worn during Thanksgiving to celebrate a pregnancy. While the original design features a cute illustration of a baby turkey inside a pregnant belly, internet users subverted the trope by replacing the 'turkey' with absurd, existential, or bizarre items. These parodies often play on the contrast between the cozy, festive aesthetic of the shirt and darker themes like 'unrelenting existential dread' or 'massive amounts of caffeine.' It has since become a staple of 'weird' internet humor, especially during the holiday season, used to mock the performative nature of seasonal clothing or to express one's true feelings about holiday overindulgence.
