Museum Nemesis

When visiting a museum or gallery, you will encounter at least one Museum Nemesis. These are the people that you see over and over again that inconvenience you repeatedly during your visit. You can tell your Museum Nemesis by some of the following traits:

-They will prevent you from seeing displays by getting up close to them, blocking your view
-They often bump into you by stepping backwards without looking. They will rarely apologise or even make eye contact after doing so
-You will never lose them. Even when you think you've lost them, they'll turn up at the next display you wish to look at
-When visiting the museum cafe they will be in front of you in the queue. They will almost certainly take the item you wanted, and it will be the last one

You museum nemesis can often be defeated by an 'accidental' tripping down some stairs. Museum stairs are often made from marble or other very hard stone.
Jim: That stupid bitch got in my way AGAIN!

Bob: Yeah man, that's your Museum Nemesis

Jim: How I get rid of her?

Bob: Trip her down some stairs, that's how I got rid of mine

Jim: You mean that screaming kid you said just fell over?

Bob: That's the one!

Jim: ...Awesome!

Nemesis Law 

When a person thinks a facetious statement is a genuine representation of a rival ideology due to their own limited worldview.

Named for the Greek figure Nemesis, who lured Narcissus to the pool where he drowned himself trying to be with his own reflection. A counter to Poe's Law.
Asshole: “Look! This gay person on Twitter says that straight people should be made into cat food! The gay agenda is real and violent!”

Reasonable Human Being: “Dude, they’re obviously joking. Calm down.”

Asshole: “…Well, how was I supposed to know? Maybe this person is joking, but most gays say things like this and they mean it!”

Reasonable Human Being: “Have you ever met a gay person? Or are you pulling some Nemesis Law bullshit?”

Fuck Nemesis

Like a fuck buddy except this person isn't your buddy in any way shape or form. You have nothing but contempt, loathing and disgust for each other as people. Yet you call them or receive a text from them every time you're lonely or they're horny and you get it on. There will be no talking, except to trade insults. You will have no need to discuss "keeping this a secret" as you're both too ashamed to reveal this to anyone.

Ex's, long term partners and co workers can all become Fuck Nemeses.
"Dear Diary,

I felt sad and lonely so I called Clive to come over and we had sex, after he called me a fat bitch. Oh, I need a boyfriend, not a fuck nemesis."

"Can't be bothered to try and pull or be nice to anyone. Time to call my fuck nemesis"

Back when I lived in upstate new york 

A meaningless, unimpressive, self-serving introduction. An indicator that the story about to be shared will be pointless and dumb.
Back when I lived in upstate new york, I also had to park on the street - on two occasions, we got enough snow, mixed with just the right plowing, that my car was lifted off the ground from so much snow being jammed underneath it.

Sister: This meeting was to discuss the rough draft of my essay, where we discussed the subsidiary questions I added in my rough draft. We also discussed the relationship between my main title and the real-life situations I chose to use in my essay. We discussed the structure of my essay as well, specifically the Math AOK section and how it relates to the contradiction of the title. This second meeting was particularly helpful in discussing the implications of my essay claims and how to apply the title across various areas of knowledge. There were many sections of the essay that could have been cut down in wordiness and the ways of knowing required further and more in-depth analysis.

Me: Woah! TLDU!
