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!

Google-sensei 

A tongue-in-cheek phrase of referring to Google's search engine. Sensei is a Japanese word referring to a teacher, or someone that is skilled or masterful in something. Attaching it to Google depicts Google itself as a teacher/professor of vast knowledge in a comedic way.
Hey do you know how tall the Eiffel Tower is?

I don't know, but why don't you go consult Google-sensei?

Frothability 

The measure of an emotional and over zealous consumer in an upwardly charging market, also known as a bull market. It's characterized by rising asset prices, increased investor confidence, and favorable growth in the markets, bro.

pod person 

A person pretending to be something they aren't, or an impostor. This is inferred because of the old alien movies where alien pods appear on earth and the "pod people" dispose of the humans and slowly reproduce the bodies, pretending to be humans.
The pod person was pretending to be my father, but I knew that he was an alien when he acted differently than my father ever would have.

A dead drop is a location used to secretly pass items between two people, without requiring them to meet.

Spies have been known to use dead drops, using various techniques to hide the items and to signal that the drop has been made. Drug dealers use this as well.

A common place is to duct tape the item to the underside of a toilet cover in a public restroom.

A signal is sometimes used as well to indicate there is something to pickup, like a pile of stones in a certain formation. After checking the drop the signal is removed.
"The dead drop is the restroom toilet at the Gulf station at the corner of Commercial Ave. and Georges Rd."

No Surprises Wedding

A "No Surprises Wedding," or NSW, is a wedding invitation designation that tells attendees that there can be no unplanned announcements, engagements, events or speeches at the wedding - all actions must be pre-approved by the couple. Anyone who performs an unapproved "surprise" will be asked to leave the wedding early.

This designation comes from Reddit, where so many stories of bad wedding behavior indicated a need to communicate expectations for the wedding behavior of attendees.
You are cordially invited to the nuptials of Brian and Tom on October 31 at noon.

Please note that this wedding is child-free (under 10) and a No Surprises Wedding (NSW). Reach out to wedding planner Sami Smith to request approvals or exceptions; please note that exceptions will be rare. Limited child care for under-10s will be available. All approvals will be noted and included in planning. Unapproved, or surprise exceptions, will result in guests being asked to leave.
