Benjimen

Someone who thinks that they are a lot funnier then they are. They often spend time messing around and never gets work done. On the rare occasion, they actually work they are also biting their fingers, making them look like mangled flesh. They also spend their whole life watching shitty anime

Steve: That guy never works he's such a Benjimen.
John: I know right, he also likes to watch really bad anime, he's definitely a Benjimen.
