look up any word, like colorful friendship:
 
1.
The kindest and coolest person you will ever know. Known to be loved by all. known for strength and courage.

The real definition of Sebastian is
"venerable" (a translation of Latin Augustus, the title of the Roman emperors)
"to worship, revere"

A GOD!!
"He is such a Sebastian"

"typical nice Sebastian"

Sebastian is a guy that is very fucking annoying. He enjoys flirting with every girl and barely has any guy friends. He enjoys piercing people with his beautiful blue eyes that I'd actually like to puncture with a stick. He steals people's phones and abuses them because he thinks it's funny. He's a badass that gets suspended from school and he makes sure he smokes at least 2 packs of cigs a day. He acts like your friend for awhile, then leaves you in the dust. He's dated at least 23 girls since middle school and you could consider him a huge whore that is just trying to get some.
Look at that kid over there near all those girls. He's being such a Sebastian.

He is stealing her phone again?! What a Sebastian!

The real defenition of sebastian is one's true boyfriend and lover but if he is not treating you rightly, one must break up with him because you would be lying to your soul and heart. sebastian is a man who usually falls in love with alexia's who are always confused between their relationship and do not know what to do.


Why would some people like a sebastian, although alexia has been waiting for him for 5 years!

An oversized penis mounted ontop of the head at proportional size to the face.

A small town in mid-Florida; nothing to do. Locals only have two things to do. Swimming, and Bingo. Run by older.. gentlemen; has limits on larger buildings to prevent them from becoming skyscrapers. Refuse to let the town industrialize.
What's good about Sebastian? Well.. it's an hour away from Disney World.
