Sinning

Playing an Assassin role in online or other rpg games.

I like playing the Scout class in video games, which in most games if you have variable subclasses might include Assassin. Since chat filters might mistake the word “ass” for cussing we use the abbreviation “sinning” for doing the assassin’s job!
