The 'It's Sodium Chloride' meme originates from an episode of the Nickelodeon animated series Jimmy Neutron: Boy Genius titled 'Normal Boy.' In the scene, a fast-food employee named Skeet refers to a substance as 'salt,' only to be corrected by the protagonist, Jimmy, who insists on using the chemical term 'sodium chloride.' The meme gained traction as a way to mock people who act overly intellectual or needlessly pedantic in casual conversations. Over time, it evolved into various remix videos and image macros where Jimmy’s smug explanation is applied to diverse niche topics where technical accuracy overrules common sense.
