Back when I was 12-13 years old I started getting to know that thing some people call “the internet”.
When I found youtube and wanted to create an account, that was the first time I had to create a username for anything, since my English skills were pretty much limited at that time (since I’m luso-venezuelan), every english word back then sounded cool so I went with “Black”. But then I thought “nah, black is too common” (teenager retardness what can I say >_> ) and changed the “B” for a “V” and switched the places of the “c” and “k”.
Now that I look back to it, the origin of my username is very stupid, but with the years it has grown on me and now i use it anytime I’m asked to create an account or the like.
