My signature is best, since it has a nice meaning and it's matching and yeah :3; And it took an hour to think of w/ him etc. Good times. :) Mine at least has a meaning unlike all of yours.
In fact, I'm going to analyse mine.
"Black and White Moderator"
it relates to the fact that I am actually the Black and White moderator, as well as the fact that Herdier is a Black and White Pokemon, and my favourite.
"Forever and an (Opposite) Day that's how long we'll stay"
it's from "Together Forever" - aka a song from Pokemon. Those are lyrics from the song. Luckily, we have perfect usernames so they match each other entirely. I thought it was pretty smart tbh.
Pair. It's a link to him, obv.
So yeah now you see why mine is meaningful and amazing.
