Fitteprins 

Norwegian word translating as "pussy prince". Describes a sneaky male person who is always able to get laid, no matter how much he behaves like an asshole. A fitteprins may also be prone to try and sleep with your girlfriend. His asshole behaviour may often be masked as white knight-behaviour, and he may also be a frequent giver of shoulders to cry on to vulnerable hot girls he wants to sleep with.

Come on, everybody knows Trond Giske is a fitteprins!

Fittering 

It is specifically the misuse or Hijacking of someone's Facebook page or "wall" for use as your own personal Twitter Page. All otherwise useless thoughts are posted to their page. You can regard their friends as "Followers", as they are exposed to all your minute by minute posts.

Guy 1: "My friend started twittering on my Facebook page, how annoying!"

Guy 2: "It's called fittering, you can do the same to his Blog (blittering) or linkedin (littering) page..."
