When you get excessive joy over your own post on Facebook. I've "posterbated" in a way, I suppose, by using joint-posts (posting two characters in one post) or by having multiple characters in a thread (in a case in which they would have to interact), but that's not deceiving or even done for my own entertainment. I do that because it's necessary for the scene/plot/etc. Because I'm both a writer outside of roleplaying and an avid roleplayer, I don't find it to be difficult at all to write my own characters' interactions with each other.
Mike was so excited about his post on Facebook that he started into some posterbation, laughing and running around.
