Sebastian's are generally funny people. They tend to laugh and joke but will be serious when you need them to be. They have big hearts. Sebastian's are the most amazing people you will ever meet! Knowing a sebastian will change your life!

THE most amazing guy you will ever meet, tall with brown hair and brown eyes. The most amazing boyfriend I could ever have. I love him with all my heart. He is funny, sweet, has amazing hair, crazy attractive, great gamer, and makes you feel so comfortable. Compliments you often and puts thought into what he says and does. Over all, he is the best person you could meet. I love you Sebby! <3
Friend: hey who's he?
Me: just Sebastian

Friend: oh he must be amazing

Sebastians think that they are awesome, whether they are or not. Some Sebastians are just obnoxious, while others have actual potential. Though Sebastians are generally good-looking, the mean ones will be horrible and crotchety in their old age, and as the years go by their penises will get smaller and smaller until approximately the size of a pea. This all depends on the niceness of your Sebastian. If he isn't a douche-bag, his penis may get even larger over time. Pick your Sebastian wisely!
Whao, that Sebastian is hot, but his penis is smaller than a thumbtack!

That guy is so nice...what a Sebastian.

A perfect and the most rarest of the rare type of guy. A total badass at times but he is very kind, caring, and a total gentleman. Has had a rough past but he survived it so that only made him a stronger person that he is today. Loves his family, friends, and girlfriend dearly and is always there for them. INSANELY beautiful, just drop dead gorgeous, incredibly hot, has the most perfect body and amazingly sculptured face. Women throw their panties at him when he walks down the street. He's also a huge video game and comic con nerd, usually goes as mister freeze.
Girl 1: "I met this cute guy who seemed distant but he's really nice and so cool."
Girl 2: "Wow awesome, sounds like he's a Sebastian."

A Sebastian is someone who is loved by all. He never fails to put a smile one your face whenever you need it. Sebastians usually tend to play soccer. They are very athletic, sweet, kind, funny, gorgeous, people with a fantastic sense in clothing. They always have a great sense of humor, a hilarious laugh, and a perfect smile. All the girls want him and all the guys want to be him.
Ooooo look at that gorgeous boy, that's got to be a Sebastian.
