Facebook guerilla
A Facebook pal who never talks to you until you post something stupid, then they come out of nowhere to yell at you like you broke their favorite toy.
You post, 'I just ate a whole pizza.' They say, 'You’re a monster.'
You say, 'I’m going to be famous.' They reply, 'You’re a joke.'
You post a photo of your dog. They comment, 'That’s not a dog. That’s a joke.'
