I am in fact not a Labour voter nor a tory voter for I... am.. not from the UK or very political for that matter.

But just for you I took a second look and in the first few frames, blink and you miss it, it says "only the crumbliest, flakiest government... Labour - Tastes like nothing ever tasted before".

Evidently some sort of meme, it is literally part of the uploaded video file, which you can confirm by downloading it with something like ytb-dlp. Nothing to do with google or subliminal messaging about current elections, your issue, well, one of your issues for you appear to have a few, is with user TheRedRag dicking about 13 years ago.

I don't get the meme to be honest but it seems to be very effective judging by your conniption. When you eat cadbury chocolate try to not consume the aluminium wrapper. :)
