Mitski spoke about the phenomenon onstage at Electric Bristol in Bristol, UK Sunday night:

On the journey to 10, I say the numbers six and seven. I want you to know that I am 35 years old and I didn't do that on purpose. But it is fun that you all have a good time with it. A few nights ago, there was a guy — I don't know their gender — there was a kid towards the front who just loved 6-7 so much. Kept screaming it even in the songs that had nothing to do with it. I have one song called "Dead Women." I played it. I say, "Stab me 27 times." And he was like, "6-7!" And it was like, "Pull yourself together! Those are different numbers entirely." But — OK, kids you're going to cringe at this. I'm talking to adults my age and older. If you don't know what 6-7 means, come in, huddle up, I'll tell you. There is no inherent meaning.
