The sound comes from Back at the Barnyard, the Nickelodeon animated series where Pig is the overly emotional, food-obsessed member of the farm crew. In the scene he tearfully recounts being bumped by Snotty Boy, missing his toast, and deciding his unicorn dream is ruined, a classic example of the show's exaggerated kid logic. The line later circulated on soundboards as a standalone crying reaction, kept alive because its escalating list format fits almost any petty disappointment people want to dramatize online.
