John Mulaney

An Asian, high-waisted, tall child with feminine hips that tries to keep burning the candle at both ends while listening to "What's New Pussycat" on repeat. His life was forever changed when he went, "Oooooooohhhhhhhhh," and, "I'm sorry!" Overall, he is the tall, lanky Irishman that got pushed by a homeless, gay, AIDS-full man, looks like his kindergarten portrait with baggy eyes and yellowed teeth, and gets confused with a woman a shit ton.
John Mulaney: I'm standing in the basement and I'm holding a red cup - you see in movies - and I'm standing there and I'm holding a red cup and I'm starting to black out and I guess someone said like, "Something, something, police," and in a brilliant moment of word association, I yelled, "FUCK da police! FUCK da police," and everyone else joined in: 100 drunk, white children yelling, "Fuck 'da' police," with the confidence of guys that have like already been to jail and aren't afraid of it anymore. You know that, like "I served my nickel! You come and take me!" confidence, but white children.

Mulattosis 

A condition defined by extreme malice toward and aversion to half of one's own ancestry. This condition only affects those of mixed race (see mulatto). Mulattosis stems from the crippling identity crisis that ensues when a mixed race social justice warrior turns their hatred for the white race inward. Other symptoms include protesting, rattling off statistics, and extreme snark.

The term was first popularized by youtuber "Atheism-Is-Unstoppable".
"That girl yelling about white privilege has a serious case of mulattosis."

Pee Calculus

When you have to pee in a movie but don’t want to miss anything, and must do the following mental equation: will the amount I have to pee cause enough discomfort to diminish my attention capacity for the remainder of the movie to an extent which is greater than the amount of the movie I would miss by making a mad dash to the restroom.
I saw Satantango last night, wonderful film but by the 5th hour I had to start doing pee calculus.
