When I saw
The Lord of The Rings for the first time, the Witch-King became my favorite character. But when I tried to create an account on an old email server I don't use anymore, Witchking was already being used. So how did I come to the x5?
During first class in gymnasium, apparently about 5 years ago, we had to chose a password for our computer account on school. I already had a nice one that no one will ever find out, but our teacher told us that it would be much safer to add like a random number and a random letter to it. Butthe x actually wasn't that random, it was more like a leftover from my old, always used nickname DomixXx, which is not referring to porn at all, but to the triple-x-movies. I had the idea from a Czech friend which I actually didn't ever meet after that (which was about 7 years or so ago...).
So yeah, the x5 from my first password somehow remained, and when I signed in at the old email server, I took the x5 as extra letters to create "Witchkingx5". And now I use it everywhere.
