Back about 2010 when Minecraft was a huge thing (is it still?) I was eating a cookie when I made my minecraft account (lol)
So I decided to name myself cookieman, which, of course, was already taken. So I added 001 to the end of it, like 007 but with a 1. So it turned out as cookieman001. I used that name forever, even as my osu name when I first started. Up until about 4 months ago. I decided to go with something simpler, and cleaner. So I came up with LeCookie.
