The sound comes from Minecraft, the block-building survival game developed by Mojang and first released in 2011. Nether portals, built from obsidian and lit with flint and steel, have been a core way to travel between dimensions since the game's early versions, and their activation sound became instantly recognisable to players. As Minecraft gameplay clips spread across YouTube and later TikTok, the portal noise moved beyond the game itself, becoming shorthand in edits for teleporting, entering a new world or shifting to a strange place.
