screentalker 

Someone who talks shit or big only behind the screen, while in person they'd use common courtesy and be polite. A person who forgets that others on the internet are real people, and says whatever they want to them without any consideration.

Mary is usually pretty polite in person, but she is a hardcore screentalker on Facebook. You wouldn't believe some of the things she says on there.

They were screentalking, saying things like "kill yourself".

Are you screentalking right now, or are you really this awful?
