I am not making any points. I have just heard this take a lot of times and I have not been around London for over 10 years. If there is a point, it is not mine.

As for its relevance: "native speakers on English", etc.

There has been quite a lot of popular YouTubers spreading this.

One of them is Kurt Caz.
