Baymax is the inflatable personal healthcare companion from Disney's animated film Big Hero 6, released in 2014. His trademark is diagnosing everyone around him with a calm, clinical voice, and this line comes from the French-dubbed version of the film. French-speaking meme communities picked up the quote as a deadpan reaction sound, trading it on soundboards where it is used to mock odd behaviour. Because the delivery is so gentle, the insult lands softly, which is exactly why the clip keeps circulating years after the film's release.
