No widely documented source is attached to this clip, so it is best understood as a user-uploaded prank sound that circulates on soundboards rather than as a line from a known film or show. Its appeal comes from the direct address to Lucas, which makes it easy to reuse whenever that name, or a friend in a similar role, is the target of a joke. Because the phrase is short, loud and instantly recognisable to French speakers, it fits reaction videos, prank edits and group-chat replies where a single crude punchline does the work without needing setup or context.
