Sebastimate

A fail way to say "underestimate", but most commonly used in the Russian community of underground (Basement dwellers) fat kids who where make-up and pretend to hack the interwebz. But at the same time look for posts via forums and try to find a problem they can take credit for without any valid proof showing that they are the ones responsible. Thus attracting the troll squad who flames them endlessly and pisses them off to the point where they either flee from the underground and seek a new life elsewhere.... or sit and try to fight an endless wave of trolls.........

However some are still trying to learn English so they post big words to sound good, but are not aware those "big words" are improperly typed. (Sebastimate, Sebestimate)

vpxsyngexvpx: ok No Problem. Us Servers Is Going Down Again Now. Cuz You Sebestimate Me.

Troll: lol Sebastimate

Troll2:srsly learn some grammar, and ask the real attackers to show up, we don't want you here anymore.

Troll3: Sebestimate me baby!! Sebestimate me all over!!!!

Troll4: The mods just have too much fun lolling at you sebestimating eachother...

sebastian sadsack

That kid that is always really sad and also strangely looks like a ballsack. Might be related to Squidward or Brass Plated Ballsack Keychains.

Poor Sebastian he will always be a Sebastian Sadsack. He will live on in Anders' fucked up mind.

Sebastian

Sebastian is the name for a really cool, hot, smart guy. Sebastian is usually the class clown, a little clumsy, awkward, and just plain dumb at times, but he’s good with his words and makes the people around him happy. Sebastian is popular at school, and has a lot of friends and an awesome girlfriend. He has freckles, a cute smile and fantastic hair. Everything about him just oozes hotness.

“Wow, he’s so funny, he must be a Sebastian!”
