A friend of mine says they don’t wanna “yuck my yum” whenever they’re about to trash something I like and it infuriates me, mildly

The expression, "yuck my yum" mildly infuriates me.
- It is definitely a face punching worthy turn of phrase
  
  Face punching is “yuck my gum”
- Definitely worthy of a subtle eye roll at least. My number one would have to be “it is what it is”. They all fall under the category of “saying something without saying anything”.
  
  But you are saying something - the subtext could be "and we can't change it". It's a way of acknowledging the situation without wanting to waste further time on it.
  
  That's politics for ya
- Never heard it before, don't want too
  
  I'm going to start using this after someone tells me a story or something interesting.
- I don't even know what it means!
  Wait: Wait, I get it now. it's along the lines of someone else's trash is someones treasure and you should not put them down because of it?
  
  It basically means 'I don't want to spoil something that you like'

"I'm not racist." is a great statement. "I'm not racist, but" is quickly entering dangerous territory.
"I don't want to yuck your yum." is also a great statement. "I don't want to yuck your yum, but" has the same problem as the above.
That "but" is doing a lot of heavy lifting and contradicting the preceding part.

While I'm definitely one to get mildly irritated at the phrasing (and am even more irritated by "fur babies" lol), I'm really bothered by people excusing their own rudeness - right up there with saying "no offense" right before being deliberately offensive. Like if you don't want to yuck my yum or cause offense then why are you about to do it anyway?
- The reason I say “no offense” is to indicate to you that my intention is something other than offending you.
  For example “no offense but your breath stinks. We should stop and get some mouthwash before we get to the party”
  I’m not saying that to make a person feel bad, though they will likely feel bad after I say it. I’m saying it to help them.
  I’m autistic, man. If the autistic kid can figure this stuff out so can you. No offense, but maybe you should consider things you don’t understand more deeply before tossing them in the waste bin.
  
  Thanks for your comment, certainly there are people like yourself who mean those words earnestly to convey a delicate point. I also imagine that comes out in your demeanor and character when you are saying that to someone.
  Unfortunately, in my experience, many people say it without any sense of empathy or compassion at all despite the literal meaning. 😕
- What about "skin dogs"
  
  Is that like the reverse of the above, used on human children?
- Yeah I agree! I usually interrupt with "offense taken" before they get through their sentence.
  Either say it or don't, but lets not pretend the disclaimer does anything other than act as a mild spoiler that they are about to say something edgy.
- Between the lines of "I don't want to" reads "I have to", which is easily disputed if said out loud.
- You mean people with "no filter", that if you couldn't handle at their worst you don't deserve them at their best?

Yeah - the whole dynamic of claiming that you don't intend to do the specific shitty thing that you then intentionally and specifically do is infuriating already, and "yuck your yum" just adds an extra layer of cringe to it.
- Yeah, I've only ever seen it used as an admonishment against someone. Like, someone says something rude as fuck and they get told "don't yuck someone else's yum" ... which, isn't terrible, when it's advice being given to people acting like children.
  Saying "I don't want to yuck your yum, but, the thing you like is blah-blah-blah" could easily be changed to "I'm an asshole and I think the things you like are blah-blah-blah" and the context of what was being said wouldn't change.

Hm. So are you saying it yucks your yum?

I’ve never heard that phrase before but it sounds like something I can use to annoy the piss out of my kids and their friends. Kind of like yeet, rizz, or cap. Especially if I use it wrong intentionally.
- Hey cap, your yeet is pretty rizz, ong smh
- Yeet makes sense. Rizz, I at least understand where it comes from (cha[rizz]ma). But I do not get "cap".

"I'm not X but <position statement that clearly requires them to be X" and "I don't want to Y but
<proceeds to do exactly Y>
" are used by people that mistakenly believe a disclaimer provides instant absolution.
On the other hand, I've never had anybody threaten to yuck my yum in exactly those terms, and I'm slightly intrigued by the prospect.

are you upset about the phrase "yuck my yum" or them trashing your food, period? I mean both are mildly infuriating to me but I'm curious
edit: added much-needed comma.
Also, I've only ever heard this in the context of food (hence the "yum") but I see it's also used for other things? Which is awful, because "yum" should absolutely never refer to anything other than food
- As a girl and a brit I'm mildly nauseated by the term "food period" but admittedly I have no idea what it means.
  
  Change it to "... food, full stop." and it may make more sense.
- What the hell is a food period? Is that like, code for diarrhea?
  
  oh... I see! That comma was very important lol

I've only ever heard this phrase from swingers and the kink community.

Where do you fall on the "fur children" way of describing certain pets? I feel like this falls into a vaguely similar group of mannerisms that probably mildly infuriate a number of folks.
- I have a cat. He is a pet. Not a fur baby or child. I am not a cat. He's too old to be a baby. Young cats are kittens, not babies. I also very dislike doggos and kiddos.
  Not sure why I wrote all that like a four year old. Maybe because that's how I view the intelligence level of those that feel the need to use that kind of language.
  
  I have a cat. He's the first cat I'd call a fur baby because he whines like a, um, fur baby.
  
  My wife has a 14-yr-old cat that she refers to as "my old man baby". The cat's mannerisms and age fit the name. That said, the phrase weirdly straddles a few categories in this discussion.
- Fur children, fur parents annoy me to no end

I'm generally unfavorable to any version of the word "yummy" in any context, so you have my sympathies.

I say this on purpose to annoy my friends, especially in situations where it's not needed
- Ditto, I use it ironically for things that truly reprehensible. I.e. "I don't want to yuck anyone's yum, but cannibalism isn't for me."

I just heard this for the first time ... an hour ago? From a Lemmy comment.
It does sound vaguely gross to my ears. Then again, so does the word "frothy" in a way I can't explain. (But "moist" has never been an issue.)

It was just said a bunch by Seth Rogen in ‘Platonic,” so you’re about to hear it even more.

his yum is probably licking ass
- Why did they make the asses so delicious?

The part that's infuriating isn't the phrase. Its a good phrase when used correctly. It's annoying that your friend is explicitly hating on your personal opinion after stating they want to respect your difference of opinion.
People have different opinions. One person's "ew" is a other person's "oooh." So never yuck someone else's yum.
