senis 

A way of either misspelling or mispronouncing the word penis which is a male reproductive organ, for those of you who are dumbasses and do not know a penis when you see one.

Dude 1: Hey man! I was having sex with a whore last night and my senis--
Dude 2: Haha dumbass. You said senis instead of penis! Haha! What were you saying? Did your penis finally grow longer than three inches?
Dude 1: Yup. How'd you guess?

Seismic Aqueous Waveform

An abnormally massive wave.
{On November 26, 2019 off the coast of Oregon (United States), 11 different satellite instruments designed to measure wave height, wave length and the direction of ocean swell systems, relayed real time and pattern delayed SAR and altimeter data providing conclusive evidence of the first ever observation of a Seismic Aqueous Waveform (S.A.W.). In the early 1800's, Sir James Clark Ross and British Naval Officer Count Fluervo of Korkyville presented an original postulate for Seismic Aqueous Waveforms (S.A.W.) suggesting that chaotic and abnormal deep sea land masses (what we now refer to as tectonic plates) were capable of colliding and dispersing an exponential quantity of kinetic energy resulting in oceanic swells up to 1950 feet high (conditions unknown at the time proximate to the mathematical equivalent/scale estimated during the Paleozoic Pangea fracturing events, circa 350 million years BC). The magnitude, span, volume and force of a S.A.W. is much greater than a Tsunami, hence a S.A.W. is also commonly referred to as a 'Supernami.'}

1. In 2019, a Seismic Aqueous Waveform was detected about 100 miles west of the California/Oregon coastline.

2. {Water cooler discussion begins} "Did you see the size of that Tsunami that nearly hit the California beaches this week?" {Conversational partner replies} "My friend, that was not a Tsunami, it was a S.A.W,, also known as a Supernami."

3. Sir James Clark Ross and Count Fleurvo of Korkyville were finally recognized for their research and position on Seismic Aqueous Waveforms (S.A.W.).

Seiso 

清楚 or せいそ
Meaning clean, tidy in Japanese.

Have been adopted by VTubers to mean Wholesome. Seems to be used ironically in many instances.

"She's a psychopath!"

"What do you mean? She's totally seiso!"

Ego-Seismic 

Thinking that earthquakes revolve around you.
From Rhett & Link's Good Mythical Morning.

Link: 'I will gladly accept being a Ego-Seismic, wherever I go earthquakes flee!'
