Coworker wrote a nice package and put it on Github, to share with other departments.

I link his package on our company Slack, mentioning a team, with text "What do you think of this one? Is it usable for you guys?"

Next thing I know I have to explain to an executive why I'm "posting pictures of seductive cartoon girls in company chat with disrespectful commentary"

It linked the Github profile picture of the developer in Slack. A fully clothed anime girl, nothing particularly lewd about it.

But I like stabbing back a bit, and confusing the fuck out of people in suits:

"Hate to say it, but a good majority of all the code the company runs on, is written by people known as weebs, who use their so called waifus as their GitHub profile picture. It is very common for open source Javascript packages, but since we recruited 50 extra devs it now also happens internally. It's not my thing either sir, but I'm afraid we have to embrace it... "

"But what about our female devs? What about Joanna, she's in your team? We have to think of diversity! Our investors are really in to diversity, we can't have a bro culture!"

"Sir, with all due respect, we have super diverse teams without even trying. The problem is... they're all millennials. They grew up on weird memes... and are probably ten steps further in embracing diversity compared to the rest of the company."

"Also, Joanna is the one who drew this particular picture. She's charging a €15 commission for profile pictures... Do you want one of your fursona, sir?"

"What is that?"

"Uh... nevermind. Let's... let's not go there"

Programmer after using go-to:

"HONEYYY! Where Are You?"
