The narrator, representing failure, vows to stand in their way and ensure their plans won't work. The repeated line, "So wait a minute if you will, I ain't got no time but time to kill," suggests that the narrator has no intention of letting the person succeed and will patiently wait for their moment to disrupt their progress. The chorus emphasizes the idea that no matter how many times the person has tried and failed before, they will continue to make the same mistakes again and again. The lines "Once a failure, twice a fool" and "You avoided everything except for me" imply that failure is inevitable and inescapable. The narrator is depicted as an imposing force, breaking through barriers ("I'm busting in") and implying that failure will eventually catch up with the person. The plea for salvation with the line "Save me, Lord, and I will, this time I got the time to kill" adds a touch of irony to the song, suggesting that failure is somewhat welcomed by the narrator. Overall, the lyrics of "Knock Knock" playfully taunt the idea of success and highlight the repetitive nature of failing. It conveys a sense of empowerment for the narrator, finding satisfaction in disrupting the plans and expectations of others.
