Instant Transmission, known in Japanese as Shunkan Idō, is a technique Goku learns from the Yardratians in Dragon Ball Z after the battle on Namek, allowing him to teleport instantly to any person whose energy he can sense. The move quickly became one of his signature abilities, returning across later series, films and video games. Online, the short teleport sound has taken on a second life in memes and edits, where it signals a sudden arrival, escape or change of scene without needing any dialogue or explanation.
