to the other anon: I don't have a source that's from the band, but in Kill Bill vol. 2 a guy uses a $20 to snort cocaine (which can give/gives you nosebleeds)+I know people used to use money to snort cocaine. Not sure if they still do, but the title could be a reference to that scene or that practice. I personally think the song at least implies that sometime you want to get high to escape life's problems, but can also mean high in the sense of constantly being on an airplane, traveling/avoiding
