As it turns out, this was part of a series of lip sync videos released by TikTok star Bella Poarch, and this one just took off. The story behind the song is a bit unexpected, though.
You see, Millie B was a 16 year old kid from Blackpool who inserted herself in the grime scene - which was (is) all about freestyle, with a focus on diss tracks. That's right - this song is a complete and total diss track, and if you look at the title of this post - I used the original title and not what it's popularly called on TikTok - it's directed at the queen of the Blackpool grime scene, Sophie Aspin.
You know, to get that information, I had to listen to a lot of grime. Some of it is awful. Some of these artists - including Millie B and, frankly, Sophie Aspin - are really really good. And, let's be clear - none of these children talking about "shitte head" are at all serious (Aspin and Millie B have collaborated on tracks after this was released).
I felt it only fair to post Soph Aspin's reply.
