In Slack you can post a reaction icon on comments. It appears under the comment really small, about 16x16 pixels. If multiple users respond with the same reaction, a counter shows how many, and if you hover the mouse cursor over the icon, a 54x54-pixel version is displayed along with the icon code and the names of everybody who made the reaction.
It addition to standard emoji, Slack also has a bunch of custom icons, one of which is classic Kool-Aid Man bursting through a wall. A co-worker recently selected this icon to respond to an announcement. I was pleasently surprised to see Kool-Aid Man in Slack, so I rolled my cursor over the icon to see it bigger. After a quick look, I moved my cursor away and the pop-up disappeared, and then the icon code registered in my brain. I thought I had imagined it, but when I went back for another look I found that it was indeed what I thought I'd seen: koolaid‑kommie. I wondered why in the world Kool-Aid Man was labeled as a kommie, and then I noticed that he was wearing a Russian-looking hat, and that he had what looked like a yellow hammer and sickle on his belly.
I extracted the full-sized 128x128-pixel version and confirmed that this version of Kool-Aid Man was made to look like a communist. I found this strangely out of place, especially since Slack is supposed to be a politically-neutral productivity tool (but to be realistic, we all know corporations can't figure this out in the 2020s). I replied in the comment thread, “Why did Slack make Kool-Aid Man into a Komrade? Is he supposed to be bursting out of the Berlin Wall like it's 1989?”
A little while later, a co-worker posted a link to a song labeled, “koolaid-komrade.” He had taken my quote and fed it into an A.I. song generator, then “remastered” it half a dozen times. It's short, but it had me laughing with tears the first time I heard it. It's really catchy too.
