1) the opposite of who you usually are and your presonality (e.g. a hippie's alter ego would be a fascist dictator)
2. the bad side of a person that may come to life at anytime, switching your personality (this is fantasy, though some people may believe they have an alter-ego in which they can't control).
3) A person who you aren't ut you act as sometimes as though you have transformed (e.g Eminem's alter ego is Slim Shady)

My real name is Tim James. My alter ego is Aaron Lewis.

digital alter ego 

A pseudonym for someone's identity on the internet. This is who they are in chat rooms/forums/online social network (facebook, myspace, etc) in contrast with who they are in the real world.

My digital alter ego got huge last week, after my definition got added to the urban dictionary front page. I got 10 friend invites on facebook today from people I don't remember.
