The line comes from the Filthy Frank universe created by George Miller on YouTube, where the villain Chin Chin confronts Frank in a series of surreal, low budget sketches. The Filthy Frank Show built a large online following in the 2010s for its chaotic lore, exaggerated characters and deliberately absurd dialogue. Short lines like this were clipped and shared as reaction sounds, and the portal explanation survived beyond the original video because it works for any sudden appearance, online or in edited videos, without needing the full scene.
このサウンドについて
The short Filthy Frank line where Chin Chin says he came through a portal, used as a meme reaction for sudden, weird or unexplained entrances.
A flat, deadpan voice delivers the line about coming through a portal, lasting just over a second with no music or background build up. The delivery is completely serious, which makes the absurd claim funnier, as if interdimensional travel is an ordinary explanation for showing up somewhere. The clip cuts in clean and ends abruptly, so the statement lands like a punchline on its own. Viewers instantly get the joke of someone appearing out of nowhere and offering the strangest possible excuse without any further context or apology.
