The Hulk is Marvel's green, super-strong hero, famous for the catchphrase Hulk smash and for solving problems by brute force. The phrase and the character have been reused for decades in comics, cartoons and blockbuster films, which is why the smash has become shorthand online for overwhelming power and comic destruction. Creators now drop this impact sound into memes, gaming clips and reaction edits whenever a character, object or argument is completely overwhelmed, keeping it popular because the reference is instantly understood without any explanation.
