The line comes from the French dub of The Goonies, the 1985 adventure film about a group of kids hunting for pirate treasure.

The brief exchange became a nostalgic quote for French viewers who grew up with the dubbed film, and short clips of it now circulate on soundboards as a ready made teasing reaction.
