Online, you know the boys is used as a short reaction and hype line rather than a full quote from a known film or show. Its appeal comes from its vagueness: it can point to any group, team, or circle of friends without naming anyone specific. That flexibility has made it handy for edits, memes, and short videos where the visual supplies the context. Under seven seconds long, it fits neatly at the end of a joke or before a reveal, and listeners recognise its tone instantly even without knowing this exact recording.
