What's the most petty, passive-aggressive move you've ever played?

I just hit the passive-aggressive Zenith.

Played a YouTube video of someone eating crisps loudly, while someone else ate crisps loudly,

because I can't be bothered to ask them to stop.

Basically, this guy is one of those people who manages to do everything that is annoying.

Whether it's banging desks,

talking loudly on the phone, laughing loudly, munching crisps with his mouth open, etc. All distracting

in our very small office. I'm not saying I'm not a prick, but I'm tired of picking the guy up

on things he should be able to work out for himself. Has anyone else surprised themselves

with their own petty behavior? As pointed out, it probably isn't properly passive aggressive.

The reason I didn't directly approach the guy is because I've done it so many times with so many

other things that he's becoming combative and resistant. I'm tired of getting into semi-pissy

debates and I'm at the point where I think

he should start actively taking responsibility for the things he does in the small office we share.

I always ask if people mind if I put on music or closed curtains, etc.

I was on the receiving end of some epic passive aggression once. I was in the 12 items or less

line at the grocery store, and as usual, had counted my items before I was in the 12 items or less line at the grocery store,

and as usual, had counted my items before I got in the line. An older couple got in line behind me

and clearly did not think I had done so. They spoke loudly to each other. I guess hoping to

embarrass me. That doesn't look like 12 items to you, does it, Marge? Etcetera, this continued on, and when it was my turn, one started,

Let's count. One, two, three.

I started wondering if maybe I miscounted,
