Obligatory “not today” disclaimer: actually fucked up over two decades ago, but found out today.
At the dawn of theinternet, I made an account on imgur. I figured (correctly) that I wasn’t going to use it often enough for the username to matter much, so I just went with the first part of my email adress and a number four times.
Turns out that there is such a thing as nazi number code and it’s never a good idea to use an even number of 8s for usernames when you’re not a nazi.
TL;DR: Didn’t know about nazi code, accidentally selected an imgur username ending with the equivalent of a double Hitler salute
There is a real Japanese company called Kubo Kenzai Kougyou. I was extremely surprised when one of their trucks sporting the company logo (which is a stylized rendition of its initials, those three letters) slowly passed by me as I stood at the bus stop. I almost laughed. Almost.
