Y hace boom circulated as a user shared soundboard clip rather than a widely documented release, so its exact origin is not clear. What made it travel is the simplicity of the phrase in Spanish and how easily it can be understood even by listeners who do not speak the language.

Its brief length keeps it easy to drop into edits without interrupting the scene, which helps it stay in rotation.
