The 'Omelette Du Fromage' meme originates from the 1996 'Dexter's Laboratory' episode titled 'The Big Cheese,' where the boy genius attempts to learn French in his sleep using a record player. Due to a skipping record, the only phrase he can say is 'Omelette du fromage,' which leads to unexpected popularity and success despite his inability to communicate anything else. Interestingly, the phrase is grammatically incorrect in French, where 'Omelette au fromage' is the proper term. The meme is widely used to represent situations where a single, repetitive phrase somehow solves every problem, or to poke fun at people pretending to speak a foreign language they don't actually know.
