I'll contribute. I refer to my wife as my "partner".

People on the left just continue conversation no problem. People on the right pause and you can see the wheels turning.

I'm a white not very masculine male.

My favorite dog whistle (that went over my head, because I was not the audience for it) was the Subaru "Come out and play" commercial.

If I remember it correctly, the ad was mostly footage of Subaru SUVs driving over rocks and through streams while a voice over talks about the cars' off-road capabilities. The ads would always end with the narrator saying "Subaru invites you to come out and play.”

As a straight man, I always assumed that the commercial was about how much fun it is to drive a Subaru up a mountain. Apparently, I was missing the point. The nature footage was all a distraction to pacify the straights. The real commercial was just the sentence fragment "Subaru invites you to come out". It was meant to say that Subaru supports queer people. It was a resounding success in promoting the 'Subaru driving lesbian' stereotype.

I'm a self proclaimed crazy cat lady. I also work in a field that has a lot of interaction with the police. I used to have a pin attached to my work badge that said "All Cats Are Beautiful".

What? I just love cats ;)

People wearing the Bad Dragon Logo

You know they're the kind of pervert that is going to be a really chill hang.

For context, the company Bad Dragon make Fantasy Dildos. And their logo looks very innocuous, just a stylised dragon.

So it is sometimes worn by folks who know that only those who are in the know will know, as a form of dog whistle for being kinky

An example of one of their products:

NSFW, giant dildo

one shibboleth i noticed is that any mention of "race" strongly indicates that the person speaking is American, especially if it's conflated with nationalities. "I'm [number]% [nationality]", any use of "mixed race", and stuff like "I can drink a lot of beer because I'm German" or "this recipe offends me as an Italian" are dead giveaways (and quite racist in my humble opinion)

The voters pamphlet was full of them. "Common sense family values" means they hate trans/gays. "Law and order" means they support ICE. "Activist judges have gone too far" means they want to be an activist judge but for the other side of the issue.

Ceationists calling it "intelligent design" rather than creationism

I always throw an occasional “streets ahead” in my conversation just to see if they’re a Community watcher. Most of the people around me are streets behind, though.

ITT people talking about Nazi dog whistles

I was voting and one of the people I looked up for judge had “EMPATHY” as a big point for her, considering a lot on the right have said empathy is bad/a weakness/the problem and judges are supposed to be nonpartisan I considered it to be a dog whistle. She also had a lot of good stuff in her background but having EMPATHY in big bold letters seemed purposeful

The narwhal bacons at midnight.

I think it's an older thing, but lace code. I guess generally on Dr. Martin boots. I'm pretty sure it died long ago, but some people still think it's a thing.

Not quite related but in a lovecraft book “mountains of madness” I think…

He mentions a “war of resubjegation” which I loved. One phrase tells a story. There was a slave revolt. If the slaves won it would be called “war of freedom” or “the rebellion”

War of re-subjugation lets you know how that war ended.

Its not so much a dog whistle but in Quebec whether you say "sovreignist" or "seperatist" indicates your camp.

Like Caesar or Kaisar in Fallout New Vegas.

Are those dog whistles? I think of dog whistles as conveying a specific message to those in the know.

The examples you gave seem more like shibboleths - something that can be used to identify or rule out being part of an identity group.

Calling taiwan "taiwan" instead of china marks the speaker as not from the PRC, but it doesn't send a specific message the way that republicans would say "welfare cheats" when they meant "black people", trusting their base understands.

Not so much a position as preferences and experiences, but the words people use to describe elements of music can often give away what they either enjoy or play. If you call a rhythm a beat, you're probably into electronic or hip hop. If you refer to a song's chord progression as "the changes," you must like jazz. If you use Italian words (outside of Italy I guess!) to talk about tempo and dynamics, you were either in an orchestra or fondly remember that one time at band camp. If a phrase is a "strain," you should get your lungs checked out. If the bridge is the "middle eight," get a colonoscopy while you're at it.

My favorite example is how francophone leftists or those who dislike america will call americans "USians". (Américain -> États-Unien)

When israelis refer to "Arabs" instead of Palestinians, a a code for untermenschen and a form of erasure.

"I have an appointment with a gentleman" is prostitute for "I'm going to shag a dude for money"

The Handkerchief code , used in gay culture to non-verbally tell what sexual practices you like

"OwO, what's this?"

"Hey buddy, if you already know no big deal. But, you know she...sleeps with a blahaj...if you catch my drift."
