Freddie often stated that pop songs should be disposable, like a used tissue. He didn't have any particular meaning in mind when it came to BoRhap - in fact, it's been documented that he presented the song to the rest of the band in bits and pieces (including his famous statement "here's where the opera section comes in!") Anyway, according to the many interviews I've read, and the small amount of personal knowledge I have of the man, I think it's safe to say that Freddie preferred for people to interpret his lyrics their own way.
