bum perfume is a luxury perfume made from the chopped off assholes of dead people. different people make different fragrances. old people smell like expired cheese, poor people farts smell like a thrift store, E-girls and only fans models farts smell like disappointed (jk they don't work because girls don't fart). farts from Florida men smell like Cocaine and farts from Saskatchewan people smell like laced cocaine but they are rare due to the population of Saskatchewan (like 7).
it is basically a pocket ass that you carry around with you all day and make it fart on you on demand for that premium smell
person one: do you want your grandfather berried or turned to ashes?
