Shemomedjamo - Georgian word meaning to eat past the point of fullness because it tastes so good or as I heard it, "I accidentally ate the whole thing."

Widdershins. It means counter to the sun's direction , and was seen as inauspicious. Counter-clockwise, before clocks.

• Paramour

It sounds fancy, but means a casual lover. A fuck buddy. A friend with benefits. Though it can also carry the implication of being an out-of-wedlock lover, as it dates back to a time where having a fuck buddy was almost certainly a sign of married infidelity.

• Kith

Means one's friends and other people they are close to that aren't family. Often paired with "kin". Kith and kin. Friends and family.

My contribution is katzenjammer, which is a word describing a really bad hangover (in the English language). I believe it is used a bit differently in the German language, but don't take my word for it.

Grandiloquent/sesquipedalian. It's what you get when you use everything in this thread ₍^ >ヮ<^₎ .ᐟ.ᐟ

perambulation is a good one. My morning walk isn't quite grand enough to be called a 'constitutional'; nor scenic and leisurely enough to be called a 'stroll'; nor yet social enough to be called a 'promenade'; 'perambulation' is just the ticket.

Overmorrow refers to the day after tomorrow

Figured the other way around might be as obscure...
nudiustertian: relating to the day before yesterday

Duodenum.

Doo-odd-in-umm.

Brobdingnagian.

It's a very big word that means very big.

It comes from Gulliver's travels. The Brobdingnagians are giants, 12 times the height of humans. The word isn't limited to that scale, but it's definitely for things that are unusually large compared to us.

It's the literal opposite of Lilliputian, which is from the better known race from "Travels" that are 1/12 our size.

It's my absolute favorite word. Not just because it's a literary reference but it's fun to say. Brob ding nag ian. It just burbles off the tongue like a drunken stream stumbling among the rocks of its bed. And, it's a big word that means big, which is just fun wordplay. Like the phobia of big words, hippopotomonstrosesquippedaliophobia, which was inevitable as soon as the idea of a phobia of big words was conceived.

No one mentioned "niggardly" yet? What's going on?

I have a double whammy: Nonplussed.

Bewildered; unsure how to respond or act. Double whammy because it does not mean not-plussed like many people seem to think.

Interrobang.

It's this thing: ‽

More people should use the symbol because it looks cool and has a badass name, so for that you need to know what it's called.

Who's with me‽

Just because it sounds cool.

"Thrice" is a somewhat obscure word that otherwise fits.

"Adventitious" is a good one. It means "non-inherent" or "acquired" (as opposed to inherent.)

Sonder (noun): the feeling one has on realizing that every other individual one sees has a life as full and real as one’s own, in which they are the central character and others, including oneself, have secondary or insignificant roles: In a state of sonder, each of us is at once a hero, a supporting cast member, and an extra in overlapping stories.

overmorgen, in Dutch. I heard this 'overmorrow' word a couple times as a response in that they wish it did exist
