The clip comes from The Adventures of Jimmy Neutron, Boy Genius, the Nickelodeon animated series that aired from 2002 to 2006. Whenever the boy genius is struck by an idea, he cups his head and yells 'Brain blast!', a catchphrase that became the show's signature. It spread through YouTube edits and meme compilations in the 2010s, then found new life on TikTok and Discord soundboards as the universal marker of a sudden bright idea, alongside other cartoon meme staples like the Dexter meme.
