I used to play GH3 on PS2 a lot and i played boss battles quite frequently
One time, in another game called Soldat, when a clan was recruiting they told me to change my old nickname since it was bizarre (i was 15 yo). I was looking for inspiration and quickly came up with Lou (final boss in GH3), added ` so i would be recognised easily while also not impersonating anyone unintentionally.
Few months passed by and i saw someone on some Soldat-related IRC channel chilling with my nickname and that person wasn’t actually impersonating me (he/she used that nickname for much longer time than me since “Lou” is actually a first name which for me, as a native polish speaker, wasn’t that obvious at the time) so that huge coincidence made me come up with an addition to my nickname - 2nd boss in GH3, famous guitarist - Slash. In the end i started using LouSlash`
As time passed by, in some places/websites/games i couldn’t use ` so i drop it occasionally.
I see what you did there
