A funny, sporty, sweet, smart, down to earth, gorgeous man. Knows how to say all the right things to turn your day around. Can bring a smile to your face with one look at him and your heart will race while your mind loses track of everything. Gives the best hugs on earth and is comforting when needed. He's the sweetest guy you'll ever meet. He can make you the happiest girl on earth. He's someone you'll never want to lose, and someone you'll never forget. He'd make the best boyfriend ever.

A lie that is so rediculous that it is laughable. A person usally jacobs to impress their friends, but it often backfires causing the friends to dislike the jacober.
Billy tried to jacob his friends, and now they all hate him. Thus is jacobism.

Jacob may not be all that in looks and he knows that, but he will treat his girlfriend like a queen, he kind, sensitive, smart, and funny. He knows how to make you laugh and he can honestly make you feel happy all the time, he is really good with words, but sometimes he total brain farts. He would never EVER hurt an animal unless it hurts them and same with a person, and he's never afraid to prove a point. He loves to play games especially Rocket League, HE ADDICTED TO THE DANG GAME, but honestly has a hard life. Even though he has a hard life, he still smiles because he doesn't want you to feel bad about him. But he knows all the time whether he'll make you happy or sad. I know this because I am a Jacob, I am not trying to say all this because I am a Jacob I am just telling the truth.
Jacob is really nice
