I wanted to make a goofy username, and I was looking at Twilight memes when I asked "what would Edward Cullen look like in a bizarro world?"
I made it around 2013, when the Twilight fad (and the hate) was dying down. I used it on two or three websites before I used it on Reddit around 2014.
I guess the PTSD is still having effect on Fiver from Watership Down.
