My nickname I was given was Red. Mainly because I always wore some article of clothing that was red. It was my favorite color so I wore a lot of it xD
Anyway, when I got to smogon the user name "Red" was already taken, so I hade to get creative. I could've done something like xRedx or something like that but I didnt. So I just added PkmTrnr to the front of Red and said fuck it lol
