Jesus or Bust!

So, I have to explain our website address. When I was serving a mission for my church in Brazil, for some reason I use to always say a phrase and then add "or bust!" (I know, I'm a dork). One time, my brazilian companion asked me what "or bust" meant. So I explained to her that it meant it was either that thing or nothing. She then proceeded to say, oh, you mean like, "Jesus or Bust!". Yes, I mean like that....Jesus or Bust!
