When you log into someone's Facebook and spam them with gross comments and stupid posts. It's like cyber bullying but with more swearing and less sense.
I logged into my ex's Facebook and wrote, 'You're a fat loser!'
I posted a picture of a dead cat on her wall and said, 'This is you.'
I commented on every single one of her photos: 'You're ugly and you know it.'
