The joke builds on two widely shared references. Shrek, released in 2001, made the ogre's angry swamp line one of the film's most quoted moments, endlessly remixed online. Deltarune, Toby Fox's role playing game first released in chapters from 2018, built a large fandom around its characters, dialogue boxes and distinctive text sounds. Fans often place familiar lines from other media into that style for a quick crossover laugh. This short version keeps circulating because both sources remain popular and the setup needs no explanation for most viewers.
