I got distracted by a pretty girl.
I think that it is certainly open to interpretation, but in my opinion there weren’t any hints about it. Personally, I could see them getting together way down the line but after forming a solid friendship and figuring themselves out. But who knows—-the story was left the way it was so that we could speculate about these kinds of things!
Many signs over the past 1-2 years have pointed to a Sleater-Kinney reunion happening soon (possibly this year), not to mention with the success of Portlandia/Wild Flag at the moment there has been great revival and growth in the S-K fanbase. So, she may be talking about Corin Tucker and Janet Weiss. Just speculation, but she definitely was choosing her words VERY carefully during this part of the interview.

I don’t know if anybody knows for certain, but I think that Carrie was 27 when she got it and I have heard that it’s a reference to some of the people she’s looked up to in rock music who were part of the ‘27 club,’ a group of musicians who died at the age of 27 (Janis Joplin, Kurt Cobain, Jim Morrison, Jimi Hendrix, etc.).
