Sebastian 

Also known as Seb, is a nasty combination of the worst things ever created. They smell, are full of themselves, bad a sports, curse a lot, and remove themselves from any social contact whatsoever. He thinks he can get any girl he wants when really, when they see him, they run away screaming. Sebastians are really ugly and have a bad laugh, smile, and body. Dont get too attached because they get kicked out of every school they go to. He is a nasty bitch that lies and is a piece of shit. Stay away...

What is that thing?
-- Oh, its a Sebastian.

SEBASTIAN 

This name is given to a guy who has weird fetish’s.
Don’t be fooled by his charm because he can be a bit of a queer.

Sebastian will make silly jokes and his ego will grow because he thinks he’s funny.

Sebastian is crazy.
Don’t be like Sebastian.

Guy1: what do you do for fun Sebastian?
Sebastian: I enjoy licking toes.
Guy1: - runs away frantically.

Sebastian 

Where do you start? Sebastian is a head ass boy who typically can be located in the United States or Europe. He looks like the old man from Up. But, hear me out... built like the boy scout dude. His workout routine involves beating his meat with a water bottle. Yes, his chode fits. Then, he goes to the gym and swims like a cebas. In conclusion, Sebastians are head asses.

Stephany: Yo, is that Sebastian.
Sebastian: Si, yo soy bebe. Come to me ;)
