Here’s some things that really bother me...
The word “sick” used to be something bad, now (to some people) it now means the opposite.
Expressing agreement by using the single word “this”, or even worse, “x2”.
The non-word “prolly”.
“My bad”
Starting a sentence with the word “yes” and then immediately following it with the word “no”.
You beat me to it. Yes. It's horrible.
“The non-word “prolly”.”
Amen!
