6-7 This is what it means

This one is pretty benign, but i'm telling you all anyway. As a father of young kids, they tend to pull out random phrases, sayings, and nonsense based upon whats doing the rounds on the social, a particularly annoying one was the Brain Rot thing, and it took me ages to work it out. Well there's another one, and it's 6-7. Basically and I'll keep this brief, 6-7 is middle of the road, it means 'Meh' as in a 6-7 out of 10, and that's it. It's big online as I think it's mentioned in a Skrilla track, and then it's been used by a Basketball player or something, anyway if your kids or grandkids or saying it, that's what it means...
