Facebook bum
A lazy human being who stares at Facebook like it's the last piece of pizza. They're bored, they're lonely, and they'd rather chat with a dog than talk to a real person.
'Hey, my dog just licked my face. I'm posting this right now.'
'I've sent 50 friend requests. None of them accepted. I'm gonna cry.'
'I'm following 200 people. I know none of them.'
