沒有擔當 is a common Mandarin expression for lacking responsibility, and as a sound it circulates mainly as a short reaction clip rather than as a line tied to a widely documented film or television moment. On soundboards and in short-form edits it functions as a piece of internet slang in audio form, a quick way to label dodged accountability without a long explanation. Its staying power comes from that everyday usefulness: responsibility, blame and excuses are recurring themes in comedy, drama reactions and commentary, so creators keep reaching for a phrase that names the behaviour in just four characters.
