Sansei 

Refers to an individual of third-generation Japanese descent.

My grandparents are from Japan, but my parents were born and raised in another country, so that makes me a Sansei.

Sayonara Zetsubou Sensei

Probably one of the weirdest manga ever penned by the Japanese. Written by the satirist Koji Kumeta, it tells the tale of one Kafuka Fuura, who discovers her teacher, Nozomu Itoshiki, under a sakura tree...

He is hanging by the neck in one of his many suicide attempts. She, being endlessly optimistic, thinks he is simply trying to make himself taller. Needless to say, this is where things get quite strange...and hilarious.

He teaches a class full of strangers, from the hikikomori, to a Disassociative Personality Disorder suffering transfer student, to a stalker, to a ridiculously OCD psychopath. And a normal girl.

The series does not take itself seriously at all, and is probably the darkest, strangest, and most disturbing comedies in existence.

AND I LOVE IT.

I'M IN DESPAIR! THE FACT THAT SAYONARA ZETSUBOU SENSEI HAS ENDED HAS LEFT ME IN DESPAIR! THERE'S NO HOPE! I'M GOING TO GO DIE!

Hyatt: 'Oh my god those grads are such sansers. Sansers talking to sansers talking to sansers'.

rusty sensei 

Someone who is a master of all things rusty and has supreme knowledge and experience in this specialized non-procreative area.

I yielded in great deference to the rusty sensei as he waxed eloquently with great depth and breath on bold concepts as the rusty trombone to the rusty ride to 50 shades of rust.

The Saneil Theorem 

For any projectile β in use in a typical gym match, involving any game with a projectile (volleyball, kickball, etc), the closer in proximity that the ball lands to Saniel, regardless of team or positive/negative effect, the more likely the situation is to go wrong and hurt the team.

See Corollary to the Saniel Theorem

The Saneil Theorem gaurantees success to anyone that hits the ball towards Saniel

Segata Sanshiro 

The best commercial mascot ever in Japan. A warrior dressed in white who beat the hell out of whoever wasn't playing Saturn. This included kids, ravers, and fish.

"Segata Sanshiro deflected the cruise missile!"

"Silly Segata Sanshiro, flips won't work on zombies!"
