Um, Yeah, What?

So why is there a song by guitarist Paul Brown called, "The Rhythm Method"? Seriously though. I don't understand why he titled a song after a method of birth control? I wonder what he was thinking about when titling the song... like what was going through his mind. The song doesn't even have sexy undertones or anything... it actually is really good driving music... so I am really not understanding why he decided to name his song after some birth control.
