Buttering the cat 

This term began to appear after the December 2021 viral Reddit post "AITA for “perpetuating ethnic stereotypes” about Jorts?" on r/AmITheAsshole by u/ThrowawayOrangeCat about a conflict involving two cats at their workplace. The cats are named Jean and Jorts, and to cut a long story short, a human colleague named Pam had been spreading margarine on Jorts to encourage him to groom himself. (Presumably he would like the taste and spend more time licking it off.) It's unclear whether Jorts responded to this, because Jean began to lick his fur -- this upset her digestive system. Pam was asked to stop applying margarine to Jorts. Readers shared the post to social media, and people began posting memes and jokes about the situation.

Later that month, #DisabilityTwitter used the situation as an analogy, to address whether a particular accommodation is useful. (Implied: even if it's well-intentioned, if it's not helpful to the person with needs, it wastes time and may actually have negative impacts. Just like applying margarine to Jorts.)

"Are you helping, or are you just buttering the cat?" (from #DisabilityTwitter)

A person may want to help resolve a difficult situation, but realizes that they lack the necessary skills and would just make things worse: "I'd love to help, but at this point I suspect I'd just be buttering the cat ..."

Buttering 

It's the opposite of a roast. While people in a roasting event would gather up to make fun of a single person, a buttering event has people gather up to adore, praise, and talk good about that person. Sometimes, it's extended to include everyone, so that each person has a chance to receive a variety of compliments. You can't talk bad about someone at a buttering event. The worst you can get to talking bad about someone is constructive criticism, guidence, and maybe a compliment sandwhich.

Coworker 1: Hey. Have you heard that the Coolerman and The Boss were feeling sad lately

Coworker 2: Yeah. They were feeling underappreciated, lonely, and unconfident.

Coworker 3: I have an idea! Let's have a buttering.

Coworker 1 and Coworker 2: That's a great idea!

Coworker 1: That way, they would feel more appreciated.

Coworker 2: A buttering event sounds perfect!

* later that day.

All: Surprise!!!

Coolerman and The Boss: This is so unexpected!

Coworker 7: Coolman is so awesome, he helped me with some paperwork

Coworker 5: The Boss is so cool, he gave me a day off when I was feeling sick.

Coworker 8: Coolman is so fantastic, he helped organize my daughter's birthday party.

Coworker 9: The Boss and Coolman are so cool, they're indestructable!
ect.

buttering up 

giving unnecessary goods/complements/sex to someone to get on their good side for manipulation purposes.

I found myself buttering up my friend the ranger, with funny pictures, before he would even think of buying the hat.

Carbon buttprint 

A brown stain found on the back of someone's underwear.

I need to reduce my carbon buttprint.

You can start by doing a better job wiping your ass.

Buttprune 

Dried feces stuck between the butt cheeks, tend to appear if you don't wipe good enough.

Did you stick it in her ass?

No, she had Buttprune.
