Can i/you be really petty? Like petty enough to snitch?

Yes.
If someone pissed me off while i'm having a bad day and i'm not having a good mood
Best believe i'm gonna snitch
Like maybe they said some type of racial slur or maybe a death threat
I'm gonna screenshot what you said and post it online
I'm not even gonna blur their name
I'm gonna find their socials and link it in my post so that anyone can see

If you're maybe asking "damn, who hurt you?" No one did.
Just imagining i'd be petty enough to show their private info if i'd ever get the chance
Then again that's just my imagination ^^
