The phrase ik kan er wel 5 op is Dutch for roughly I could manage five of those, and the clip circulates online as a standalone reaction sound rather than a well documented quote from a film or show. Its spread comes from Dutch speaking meme pages and soundboards where short confident lines are reused out of context. Because the meaning is simple and the number five is easy to visualise, creators pair it with food, drinks, workouts and games, keeping the joke alive long after the first uploads.
