Do people think I'm a Little Mouse

lol.
Just look at my username LogitechMouse. Can people judge me based on my username

.
Wait a minute!!! You two aren't brothers?

I'll agree with Loycev on this, if you choose a random name that basically means nothing it's clear you don't care about making a statement with it, but if you choose one with gunman, p**ywrecker, Smoochy Woochy Poochy this does make a first impression you're going to have to work a bit to change.
Speaking of names, I remember
the story of how people who named their kids after GoT characters before seeing the end felt after that. You might name your kid something that sounds cool only to find two years later his character turns to be stupid or a villain, or even worse just when you think you have found a new cool name for your daughter a wanna-be pornstar thinks the same.
Ps,
Interpol is searching for 41 Jesus, funny enough they aren't searching for a single Judah.
