The feeling of an obscure, distant, detached and almost non-existant memory, and you could almost describe this feeling as nostalgic, but something more than that (like how Deja Vu is a feeling like you've seen something before, except it is more than that). This is often triggered by viewing a building or room with a certain pattern or color. It is one of those feelings that we cannot convey with any form of language.
I felt 'ophorne' when I was exploring caves in Minecraft, I walked into a certain cave, and the way it looked, I felt a certain feeling I just could not explain to my friends I was playing with, it was almost like an obscure, long-forgotten memory that I just couldn't grasp. Luckily my friends understood what I meant.
Ruler of Lake Titicaca. Rumored to have a bunghole that gets very angry if it does not receive toilet paper. Cornholio the Great is often seen walking around with his shirt over his head and his hands in the air, chanting songs about his power, and his bunghole.
"I am Cornholio! You do not want to face the wrath of my bunghole, for I need TP!"
Butthead: Shut up, Beavis! (uh huh huh huh)
Beavis: Um, okay. (heh heh heh heh).
