'character' = 'toon'. when and why?

[gotrocks]

not 100% sure on the toon thing, but my assumption would be that it came from cartoon, as back then most mmo graphics could be considered 'cartoony'.

mob is easy, that was a term from the MUD days that was short for mobile object, or often just mobile. If you've ever played any MUD, you know that every. single. thing. that you can kill is a mob.
