A Jacob is typically a small insignificant male who absolutely despises himself, but is also okay with himself. He always feels like shit, but he always acts like he is fine because he doesn't want to burden people with his issues. If he has siblings, he loves them to death and always wants to help them with their problems. He makes terrible, and I mean terrible jokes because he knows they're terrible, and he does it to annoy people. A Jacob is usually a charming individual, who can convince most people to give him what he wants. When a Jacob is depressed, he fabricates a thought that everyone should hate him, and he will go out of his way to make people hate him. He can seem like a terrible friend at times, but when you really need him, he'll always come through.

Get the Jacobmug. 
Get the Jacobmug. (This applies to some Jacobs only) Rude, inconsiderate, a backstabber, and has the filthiest mind around. No really, he won't shut up. Ever. He constantly makes fun of you and doesn't like you for who you are. He and his brainwashed drone tend to walk around the school making gross, impolite, or unfunny jokes. If you see a Jacob, make sure he's one of the good ones before you talk to him. This kind I'm describing will usually think that everything he says is hilarious and that everyone loves him. He apparently doesn't know how to apologize, and believes that he's never wrong. Oh yeah, and the bad Jacob likes to spread rumors and start drama. Be careful around Jacobs, some can be really cool people but others...
"Hey did you see that new kid, Jacob?"
"Yeah but I think he's one of the Bad Jacobs."
"Why?"
"Let's see, he makes fun of everyone he meets, he won't quiet himself for one second, and can't stop making filthy jokes."

Get the Jacobmug. He's the kid you always want to be friends with. He's hot, loving, and a athletic. He's the popular kid in your school and if he talks to you you go from a demon to a angel.

Get the Jacobmug. A person who is known as 'Jacob' will seem kind at first, but actually turn into a dragon at night. They know much about geographic issues, modern history, literature and various aspects of drama. People named Jacob are attracted to Japanese girls Nodoka, typically have blonde hair and blue eyes, and also enjoy singing in their past time. He talks with a Japanese accent most of the time, whilst luring girls into his tutoring business to only change into his dragon formation to eat them. Beware.
Kim: Jacob offered me some tutoring yesterday, I didn't want to accept as there has been a mysterious pattern of girls going missing after his tutoring groups.
Bridget: Yes I have noticed that, my mumma warned me about those dangerous boys.
