i was looking for a good Japanese-y sounding name for my twitter account, and the UN: Sinikuro seemed to have a nice ring to it and so i stuck to it...
a while back, i was part of another forum that had nothing to do with pokemon (it was a minecraft server) (this was like 5 years ago i think)
and i chose the name "uhduh13" why, because i was a pretty sassy person back then...LOL
if someone was to really dig deep into my history, around a decade ago, i was on club perguin *gasp* and i was really young back then, back then i was into the anime *gasp* Naruto and as my simplistic childhood mind could figure out, Sasuke's chidori is *gasp* blue! so on club penguin, my UN owen was her? was "BluThunder12" yep.
TL;DR:
Present: Sinikuro
5 years ago: "uhduh13"
a decade ago: "BluThunder12"
