Bruises

This song means a lot to me, because i'm in a relationship like this. :)

I think this song is about love, and about how sometimes you'll do anything to make the other person in the relationship happy, even if means doing difficult things and having to say "I'm sorry"(example-doing handstands when you can't, trying to ice each others bruises, etc). I think the bruises might symbolize the marks that your significant other can leave on you, good or bad. The girl starts off by singing to her lover that she's constantly black and blue for him, meaning that he's left his mark on her for forever basically.

Later on, the boy sings back about how he wants to fix the "bad" bruises he left on her with the frozen strawberries, which means to fix their problems or maybe be forgiven for past mistakes. (It kinda seems like she the one doing all the "handstands" or putting all the effort into the relationship, but that's just my personal opinion though, lol) He admits that he's black and blue for her too, and the feelings are mutual. 

Those feelings are good feelings though, because the repetition of how black and blue they both are makes it seem like the boy and girl are incredibly happy with each other, good and bad, in the end. The dark bruises and holey jeans are the hard times they've shared, but these are intertwined with the grass stains and pink bruises, which is the fun and joy they've had.

Basically, it's about loving each other, remembering everything, and working through the good and bad. It's Commitment. :)
