Flying bum is a song that features a pair of butt cheeks flying through the air wearing a super hero cape, and his super power is shooting different types of poop/farts from his butt, shoots it at criminals and other kinds of troublemakers, as he literally is nothing other than a butt (appearance-wise), but he's also a hero as he has even saved some people from being murdered, by literally knocking down the person or people trying to murder the victim or victims by shooting them with big turds. "Dispensing his brown justice on you" that talks about how he fights criminals and saves the innocent from the criminals, and why it's called BROWN justice, because poop is brown (usually), right!? 💩🍑
