False bravery that comes from hiding behind a computer screen. Includes (but is not limited to) saying things that you would never typically say in a face-to-face conversation, making empty threats to people you don't like, and/or making up lies just to get a rise out of people (also known as trolling). These individuals are usually quiet and backward in public, but talk shit about everyone they can while they are on facebook or another social networking site. When confronted in person, they back down almost instantly.

when you've done something so cringe you can't stop replaying it in your head and it stops you from getting on with your every day life
