Many good questions generate some degree of opinion based on expert experience, but answers to this question will tend to be almost entirely based on opinions, rather than facts, references, or specific expertise.

  • Welcome to EL&U. The interpretation of poetry, song lyrics, and other artistic forms is subjective, and thus ill-suited to our format. There are various other sites devoted to song meanings, though (SongMeanings.com, Lyreka, Songfacts, r/SongMeanings, and so on), and I would advise you to try there. For guidance on what topics are accepted here, please review the help center. – choster Feb 16 '16 at 16:28
  • @choster thank you for the websites... And will keep this in mind :) – brainst Feb 16 '16 at 16:49

It means that one word has the capability to hurt you or make you elated. Say your lover in all his/her seriousness says something really hurtful, the expression "heart open" means every word they say impacts you emotionally. "Heart open" implies vulnerability here.
