'Texting speak'...mixing numbers with shorthand words ie. msg4U. Also 'plz', I loathe that one almost as much as a former commodities trader who recently took part in a TV jungle based show.
Also, using 'Z' in place of 'S' in words, largely for the reason you posted the image ie. 'treads' becomes 'treadz'. Yep, naff.
Daft lines on telly. That bit in the opening credits of 'Knight Rider'...'in a dangerous world of criminals who operate above the law'. Eh?...they're criminals, unlikely to obey the law!.
Clickbait articles ie. 'this is (insert celebrity), how they live now is awful' and my 'favourite'....'Russia drilled this borehole and sealed it up because of the shocking discovery...'. I'm a geologist, I know the hole in question, the Kola Superdeep Borehole. It was abandoned mainly because they cash dried up. There is no shocking discovery. On a seperate note, I saw an article in the comedy 'newspaper' Daily Star the other week announcing that the Chinese are drilling to the centre of the Earth....FFS...no they aren't. In the age of Google & Wikipedia, journalists are getting lazy.
