Usually when I dont depress the clutch pedal long enough or at all they start grinding..you know what they say tho 'cant find them, grind them.'

People that chew really loudly when they eat. I don't mind slightly noise but some people just chew outrageously loud, it is so frustrating and I cannot eat whilst they next to me.

Surely they must be aware?!

People who pull out in front of you while driving, then proceed to drive under the speed limit, had they waited 10 more seconds, nobody is behind me.

This really grinds my gears

What really grinds my gears?  I'd have to say "Cowards & Backstabbers Grind My Gears".  So many of them. Both in RL and Non-RL. Everywhere ya turn, seems someone has an axe to grind and they grind it the dirty way.  Amazing, and things in this world just get worse and worse. I feel bad for the kids growing up these days not knowing who the hell they can trust and who they can't.  

You know what really grinds my gears? Two rusty wheels with metallic teeth turning on each other while both are lacking WD40

That really grinds my gears

People who think the rules do no apply to them, and yell at the poor worker who is simply doing their job. (Yes, I am bitching about you, the fat redneck who had the poor teenage girl in tears at the grocery store today when she told you that you had to wear a mask.) Stupidity and entitlement just amaze me. 

The amount ob conspiracy armchair you tube specialists that try to tell you how good the government is at hiding things but it all can be exposed by watching this you tube video by some tin foil hat wearing racist fuckwit called Sargon of Akkad.

Why rely grinds my gears is that last year, I should have been tested for my diabetes but its wasn't until this year I found out 

People who apply double standards, such as telling us to expect to go down with the crew when we are hands and yet there are people who are hands and instead of going down  with their ship they move to another one and are placed in hand positions. 

inertia

Cobwebs.  I work nights, doing deliveries...and the summer means loads of cobwebs.  Guaranteed, if there's one there, I'll walk face first into it!

People walking along with their phone on loud speaker but holding it up to their head because they cant hear it! Use it as intended and you might get somewhere!

When people shout about the sentences Judges hand out when they know nothing about how the system works, or that Judges have strick sentencing guidelines that they can't stray from, based on criminal record, aggravating and mitigating factors and whether it went to trial or contest or whether the pleaded guilty and when they pleaded.

The words "Lunch" and "Moist". People who overuse words unnecessarily, especially words like al-fresco and totes amaze...

I mean I could go on to be honest, there's so many things. I guess I'll keep the others for another day! The problem posting this was which ones do I pick today haha.

What really grinds my gears is when you go above and beyond for people and they don’t give you the same courtesy. It’s so frustrating sometimes treating people the way I’d like to be treated only for them to not appreciate it and return the favor. I personally try to be overly kind to everyone at first, but more often than not people are shady and end up not being worthy of it. 

People who use the word 'like' in a meaningless way almost every other word. It seems for some it is almost like a tic the amount of times used. It's usually followed up with - do you know what I mean?....like? Winds me right up.....like.....
