Sebastian is the most amazing boy you will ever meet. He patiently listens to all of your rants and always knows what to say. He plays a lot of musical instruments very well, and usually has an amazing singing voice. A Sebastian always knows how to make you laugh and tries his best to understand you. A Sebastian is always there for you. A Sebastian is somebody you can trust with anything. Sebastians are usually quite shy, but when you get to know one, you would never find a better friend.
Cherish your Sebastian.

sebastian is a type of guy who will always be by your side and will always help you in a heartbeat. he is not incredibly dumb but also not very smart either but hes 100% weird which makes him more funnier than he already is. sebastian has gone through a s#@tty life and woud kill himself(not literally) to make other peoples pain stop. he may be a little chubby and he may not think that he look good but hes a really nice guy even tho people see him as a annoying piece of crap,well thats a complete f#%king lie.

Get the sebastianmug. A handsome young man who has the perfect girlfriend called Megan, who loves him to the bone and it is the same way with Sebastian. He is really brave and has a mad sense of humour, he will grow up to be a wealthy man who loves basketball and rugby sadly at the age of 14 or 15 Megan leaves Sebastian but that could always change depending on Megan's choice. Sebastian makes a drill song at the age of 11-12 because of his passion to be a driller. This might not go well for Sebastian but it depends on his choice's at the age of 16 Sebastian will go to prison for graffiti and vandalism but this is only for 23 months.
GIRL 1: Did you see that roadman on the bus he looked like a driller but he was pengggg.
GIRL 2: He was probably a sebastian.
GIRL 2: He was probably a sebastian.

Get the Sebastianmug. The buffest chad in the yeargroup. He can bust anyone up if they mess with him, but he doesn't want to. He is really fucking annoying, but can be sweet and caring. He is also very brainless, and will sleep everywhere. When he gets pissed, he will fucking obliterate you. Dont. Mess. With. Him.

Get the Sebastianmug. An amazing friend with a heart of gold. A person who may not see himself through the eyes of others, but to many, and to one, he's perfect. He would sacrifice a great deal to help the people he loves, and will always be there in a heartbeat if they needed him, (even if they don’t help him in return). Someone who is the most beloved person anyone could come across. He's dearly loved although he may not know or feel this. As soon as one meets him, they would immediately realise he's very special, and is a person who will eternally be there to carry them through the good and hard times. His understanding nature could brighten anyone’s and everyone's day, especially mine. Anyone who knows a Sebastian is a lucky, lucky person and they should never ever take advantage of his kind and caring personality. He's someone who is so wonderful in every way and it would be impossible to find anyone like him.
Sebastian is the best
