Friendly to all, but only opens up to those he's really close with. A good judge of character by most people's standards.
2. Usually an exotic breed, of a foreign background. Most often fluent in more than one language.
3. Having statuesque features, like that of a Roman God; devastatingly good-looking.

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.
