We use HipChat at work, which is sadly not as hip as Slack. Although it is made by Atlassian, and they are an Australian company, and marsupials are pretty hip (except the very unhip echidna--get it together, echidna). If you want to appear edgy and kicky and down with the kids, you can use these curious image things called emojis in your chats to your coworkers. Weird, I know, but stay with me here.
If I start to type "(thumb..." I am presented with 3 type-ahead choices: (thumbsup), (thumbsdown), and one more--can you guess what it is? (thumbsideways)? (polydactalthumbsup)? No! It's (corpsethumb)! Corpse thumb? Why is that an emoji? Not to mention that the Corpsethumb is only available in the up position! If I was a corpse, I feel secure in saying it would be a thumbs-down situation. Or really more of a thumb-hanging-limp-and-lifeless situation really.
Why not a (handofglory) emoji that would render the receiver catatonic so you can sneak out for a well deserved drink or two until they recover and start sending you more annoying messages to prove that they are actually working and not screwing around looking at pictures of cats.
And if there is not a black metal band called corpsethumb, there really should be.
