Before anyone asks, it means nothing.
It just the way I create usernames for websites (so I don't forget them :P).
Examples: stufafpassw, stutwipassw, stuskypassw, stusncpassw, etc.

If I could I'd change it to "Charr!" but FA doesn't have such feature. I'm not going to migrate to a new account just to change my name (at least not now; there's too few of you to redirect you to a new account).
