When I first started using a password manager (KeePass!), I for some reason got the bright idea to name everything using two-letter codes -- reasonable ones for less important things, like AG for audiogames.net, but nonsensical ones for more important accounts -- to ... make the lives of my attackers harder, I guess? I've since changed that into normal names. Recently, I even realized that hey, autotyping is really good actually, and putting the URL into each entry might come in handy sometime. But even now, there is still one two-letter combination that I myself no longer understand. The password was hand-crafted, rather than generated, and I remember making it, but heck if I know where. This must've been an important account somewhere, because I even set it to expire. But even though it has, I shall never be able to change it, and it shall haunt me for evermore. Moral: Be better at determining your threat model than me, please.
