The lyrics repeatedly contrast people who seem confident with people who may not understand what they claim to know. The speaker sounds mocking and frustrated, especially through the repeated exclamation. There is little change in the mood: repetition makes the criticism feel insistent, almost like a chant, rather than telling a story with a clear beginning and end.

“To strut” means to walk in a proud, showy way. Here, it suggests that the people are displaying confidence or importance, perhaps without having much understanding behind it. The phrase “they know what is what” means they seem to know how things work or what matters. But the repeated contrast—“they don’t know what is what”—undercuts that appearance and questions how reliable their knowledge really is. “What the fuck?” is a strong, informal expression of anger, disbelief, or exasperation.

The lyrics leave the people unnamed, so it is unclear who is being criticized or what subject they supposedly misunderstand. The speaker may be accusing them of being shallow or merely pretending to be knowledgeable, but the words could also express general irritation at people who act self-assured. Because the same lines return so often, the song’s force comes less from a detailed argument than from its rhythm and repeated contradiction.
