fleren 

The ship between two lovers, Floch Forster and Eren Yeager from the anime and manga Attack on Titan. It's a gay relationship between two men who bounded themselves through the desire of saving their homeland and countrymen.

In the beginning, Floch didn't like Eren because he stood out for his childhood friend in the Serum Bowl event during RtS Arc. However, years passed and they banded together forming the Yeagerist faction, a paramilitary group who would take control of Paradis and rescue it from certain doom. Once Eren activates the Rumbling, he's separate from Floch, who's in charge of taking care of Paradis' internal issues.

A group of traitors and enemies is formed, they fight the Yeagerists and Floch is injured - the traitors escape using a boat. Floch is revealed to be hanging on that boat to try one last stand, which ultimately fails but causing the death of Hange Zoe. Even in his dying breath, Floch still entrusts Eren with saving Paradis...

flergeflamming 

Teachers or authority figures going out of their way to talk effusively and positively with young children about homosexuality and transgenderism, usually without parents' knowledge or permission. Synonym of "grooming".

I don't care what you want to call it, call it flergeflamming for all I care, just stop normalizing sexual discussions with children.

Flerken

The cat like alien creature that Captain Marvel keeps as a pet. While it may appear as a normal cute Earth cat, inside it's mouth contains a shit ton of tentacles, smaller mouths and even pocket dimensions and bubbles of time.

Rocket Raccoon - *Trying to kill Chewie the Flerken* You have a Flerken on your ship!
Captain Marvel - That's my Cat!
Rocket Raccoon - That is not a "cat"! That is a Flerken!

Flergenfleuf 

the overuse/overexamination of a word to the point where it no longer seems like a word, or it becomes alien and strange.

1) "I just had a flergenfleuf with 'stupid'"

2) "after I read Heidegger's 'Being and Time' the word 'being' became flergenfleufed"
