People who talk like they are tough over the internet who are in fact cowards in real life.
Tough typers like wild_believer was acting very brave until I confronted him in real life.
Person who follows you on a social network that gets you to follow back then unfollows you just to get more followers.
Bubbles just followed me on instagram. I'll follow her back. Bubbles unfollowed me but I am still following her. What a social network dirtbag!
