The clip comes from the Thomas the Tank Engine children's theme, remixed by online creators into the bass boosted and earrape format that spread across meme soundboards and short video edits. Boosting the low frequencies and pushing the volume into distortion became a common joke treatment for innocent songs, similar to how the MLG air horn was used for exaggerated emphasis. It remains popular because the source is instantly recognisable, while the harsh boosted version signals irony, chaos and a deliberate prank on the listener.
