Wallace and Gromit are the stars of the beloved British stop-motion films by Nick Park and Aardman Animations, and Wallace is famously devoted to cheese, especially Wensleydale, which explains this clip's title. His catchphrase, Cheese, Gromit!, is one of animation's most quoted lines. This particular nauseous moment took on a second life online, where meme editors stripped it of context and turned it into a universal reaction sound, like the Bruh meme, for gross-outs, bad food and regrettable choices. It endures because Wallace makes even being sick sound charming.
