It's called sarcasm. When you say something stupid, wrong or bad, but don't mean it seriously. Sometimes I think I need to write (sarcasm) at the end of every message.
I really don't like repeating myself but for clarities sake here is one of those times it's justified.
You aren't very good at it.
Not only does sarcasm not convey very well into text, you need have wit to pull it off. Even if you'd put a bright pink neon sign with pretty sparklers and clowns all pointing at the giant glowing words of "SARCASM" .... it would still have been a terrible attempt.
Sarcasm, whilst being the so called "lowest form of wit" is quite clever in how it's used by people that know how to use it.
"they are so fucking annoying I would kill somebody" is not witty or clever. Saying something dumb then saying it was sarcasm isn't how it works.
