What does your Username mean?

every one calls me that at school so i figured why change my name on a forum site

Fallen Hero. A lost soul who has fallen from glory. Lost it all and still goes on everyday. Makes his way through the day wondering what has gave up. Not sure if he makes the right choices but does them anyway. Keeps going with what little hope for the future he has. Never knows if today is the last day he every wakes up.

well, my has no meaning. it is the name of that girl from Fullmetal.
