The name combines Gin-san, the familiar way fans address the silver haired lead associated with this style of anime comedy, with dora, the large gong heard in traditional Japanese theatre. Online, the clip circulated through soundboards as a compact reaction sound rather than as a full scene, which helped it travel into short edits and remixes. Its appeal comes from that cultural contrast, mixing a formal theatrical cue with modern meme pacing, so even viewers who do not know the reference understand the dramatic pause it creates.
