The more annoying ones are those where the substitute words without even shortening them; words like “boys” will be changed to “boiz/boix”, or “phone” being changed to “fone”.
I don't really understand why some people do this. Shortening words reasonably is to save time and possibly space. However, it's unclear the motive behind distorting spellings of words indiscriminately.
As in ehn... it just doesn't make any sense. And it's not as cool as they think it is.
It's definitely not.
