An internet bot which passes as a woman when posting spam. Very common in social networks (such as Facebook and Twitter) and porn sites, these bots use pictures of attractive women as avatars and simulate innuendo and some interest in the user.

fabotage 

A blend of the words 'Facebook' and 'sabotage'. Fabotage is an alternative to 'frape' (using someone else's Facebook profile without their knowledge and posting content or changing information, often with humorous intent) that is more fun to say and doesn't trivialise rape.
"Well, that was a witty fabotage! I will fabotage you back, just you wait."
