Oh dear, you're either very unobservant, Nigs old lad, or you don't read very much, or you're as dim as a Toc-H lamp - your choice as to which of those apply. Whichever way, even though it's perfectly clear to everyone else (except perhaps The Troll of Hertford), you don't seem able to get it, so I'll set it out for you in words of as few syllables as possible.

It's a collection of the mis-spellings of semi-literate BrexShit-Bumpkins which, I have observed, have abounded, not just on 'B*****n F***t garbage, but across innumerable Internet forums and social-media sites, ever since the BrexShit debacle began back in 2016. They are not my mis-spellings - I actually paid attention at school - they are the the mis-spellings of others! Including the one you labelled as 'crude', hence the inverted commas to indicate that fact.

Now, hopefully, the light might be dawning for you, although there are a few big words in there - let me know if you need me to explain what they mean.

But, of course, you already knew all that and you were just pretending to be stupid, weren't you?
