Words changing?

So I’m trying to reply to all my threads and some of the words keep changing to stupid variations? At first I thought my computer had a virus but I went on my phone and it’s done the same thing, as well as on my iPad.

The words are highlighted in blue with the variation over the top (tongue became flicky licker, child became ankle-biter ect) if you hover over the word with your mouse it shows the original word.

I don’t know if this is supposed to be happening or is some kind of prank but it’s strange so thought I should mention it :)

Fuckin hell I thought it might be but because it's so far into the month I didn't give it much thought

I thought I was losing my mind, jeez
