I mean “bumptious and peevish” just do not work anymore.
The scales have fallen from my eyes.
Wow. Major Revelation. Thank you. I will have to revisit my visceral revulsion / contempt for “on accident”.
My refrigerator has a temperature control dial that goes from 1 to 9. It includes the helpful note “9 = max”. Does that mean the highest temperature, or the maximum amount of cooling?
Aaaacccckkk. My brain hurts.
I’ve read my owners manual(yes I did!) It never says what the fridge means to tell me.
My assumption would be coolness, but I wouldn’t wager too much money on it. (Though I would bet it is in that direction.)
Agree w @pulykamell that’s the way to bet.
I just checked and my fridge has electronic controls. There’s a bar chart-like display of 1 to 5 lit bars. Push the temp control button to increment the number of lit bars and after it gets to 5, the next push resets to 1. Helpfully the printed legend at the 1 end says “cold” and the 5 end says “coldest.”
So no confusion but you do indeed turn it up to make it more colder. 
Aren’t “slow up” and “slow down” the same thing?
I’ve heard “hold up” used as a synonym for slow down, but not “slow up”. Hopefully that isn’t another change that will stick that I’d have to get used to 
.
“Sit down” and ”sit up” don’t mean exactly the same thing, bit you can’t sit up without first sitting down.
I first started encountering ‘Salty’ in the modern meaning when I was around the fringes of the fighting game community (Streetfighter, Tekken and the like) about 2013. There was a thread called ‘profound saltiness’ where people would post their opponent’s angry pre-ragequit chat screeds. I don’t know if this was the originator of the term or if it came from other online communites first, but it has spread to online spaces and even offline since.
To be salty is always to be openly angry , maybe crying tears of rage. This is what differentiates it from ‘Bitter’
Me too.
I’m going to start saying “by purpose.” 
You could use “by design”, which means basically the same thing, but sounds more badass.
If salty came from something like street fighter talk, it would mesh with “salty language” which is just what might be expected from sailors of old.
“All at once, you are using language that would make a sailor blush” from My Fair Lady. Professor Higgins opining about the effects of allowing women into one’s life. Which does bring bitterness into play.
Otherwise, prior to this thread, I would have guessed it was a reference to salty tears. But it seems I would have been rather mistaken.
A personality might be sour, and an emotional state might be bitter with respect to something. But usage changes.
Without going into details or examples, I always thought of bitter as being more internal and salty being more of an external expression of feelings.
I’m going with “peppery” from now on.
In my experiences and usage of the words, that’s exactly a major component.
Very different usage. I think of salty as primarily being blunt with a little touch of pessimism. Bitter is just nasty, mean and resentful.
Another way is that “salty” is more annoyed, peeved, usually temporary, tied to a specific event. “Bitter” is more deep-seated, lingering, resentful, stronger than “salty.” Maybe like the difference between being “sad” about something vs “depressed.”
I think that’s a good way to describe the difference.
I don’t recall hearing salty used with a meaning described in this thread.
I’ve lived in Asia’s since 1990 with less interactions with native speakers since less and less daily interactions with young native speakers.
If I didn’t have the Dope, I would know nothing anymore.
