The exact original source of Zhi Pen is not documented in the information available for this clip, so it is best understood as a short online sound rather than a line from a known film, show or song. Its name uses the Chinese characters for direct injection, and its slug and short seven-second length suggest it circulated as a compact, easily shared reaction clip. That brevity is why it fits short-form edits, where a quick sound can mark a change of mood without needing context from a longer source.
