The exact origin of this gibberish clip is not documented, so it is best understood as an internet reaction sound rather than a line from a known show or film. Its appeal comes from the familiar shrug emoticon it is named after, a gesture people use online when they have no answer. Shared through soundboards and short-form video edits, it has become a handy shorthand for confusion, indifference and playful nonsense, and it stays popular because it fits almost any awkward moment without needing context or translation.
