Post people's usernames here. Forum or ingame. Any reason, really; funny, stupid, weird, or makes a good catchphrase.
Some examples:
Icanbreathefire!
GoWest!
I will murder your dog
Baldspot
Pcon7 (note that this was a horribly failed impersonation attempt by an idiot)
Public said i commute
Any username that sticks in your head, really.
Edit: Should have said this earlier, but don't post your own usernames. That's just shameless self-promotion.
