Redditism 1: "It's the internet. You are allowed to swear." 
I hate when some very grown-ass adult says that because someone didn't cuss enough for their taste. I swear all the time in my posts here but I still find that shit really, really tryhard and it seems more immature than not saying the naughty word to me.
Redditism 2: Ending a rebuke with a question mark when it's not a question to make it sound extra snippy.
I've heard this being compared to a "vocal fry" and maybe it is, and coming from CA, vocal fries were often said out loud as a form of subtle hostility toward people perceived as lessers, such as retail and restaurant workers. If you need an example of what I'm talking about, it usually goes something like this:
Poster: "I think (opinion)." 
Redditism enjoyer: "You're wrong?" 
Redditism 3: "Do you need help? Who hurt you? Help is available if you need it, buddy!" 
This one is the worst one I can think of right now because it contaminates even the very possibility of showing sincere care and concern for someone else. It comes loaded with the implication that the person that was "hurt" or "needs help" is fundamentally wrong and should shut up. Fuck that ableist shit, forever. 
Fry and HRT are different things, fry is the low register "croak" that is viewed as negative if girls and young women do it, but positive if older men do it.
HRT comes off as someone saying something but they're not confident about it and are groping around for some sort of approval or backup (for better or worse)
I hated it when older men did it at me, especially when I was toiling for minimum wage and they were venting their divorce dad frustrations at me.
I find it kind of attractive every which way, but also yes
It might be a context thing for me, like if I was thrown from my bed and tormented every night by someone wearing a cool hat.

I am also gathering stories from my new place of work (Drafting office, mech eng)
Sounds like worthwhile reads in the making.
Mostly slop, just the most brain dead liberal take about everything.
Also the sales reps at the defence company I was at had star sign conversations. Also it sucked in a really bureaucratic way (everything was mediated with Microsoft systems, no admin or even ability to use an ad blocker, so if I looked up an instructional video I had to watch a bunch of ads). The work load and standards of work were extremely low, so it was cruise in other ways. I ran pretty roughshod with restricted information (wasn't given anything classified to handle)
Fear and Loathing at the Military-Industrial Job Faire
Also engineers think of themselves as smart, but uh... They might be good at a few things but holy shit do a lot of people in the field have problems connecting nominally distant bits of information together.
