Twenty One Pilots

Two guys from central Ohio, Tyler Joseph and Josh Dun, that make some of the most amazing music that will ever grace your ear drums. They don't want to be heard, they want to be listened to. If you're looking for a crazy, high evolvement concert with plenty of sweat to go around and crowd surfing galore, by all means, go to their next show!

From their website:
"Basically, we are all responsible for the preservation of our personal joy; but happiness is different. Joy is not circumstantial, happiness is. You can be depressed and still have joy. You can be suicidal and still have joy. We all stop thinking and we all stop talking and we all stop sharing and we all stop creating, because by doing any of these things we quickly find out just how unhappy we are. But that's ok. That's normal. Don't let the fear of unhappiness cripple your pursuit of finding what it is you believe. Since joy is found in belief, we all have to push through unhappiness to find joy. Basically."

Twenty One Pilots

A band containing two people that make music with happy melodies yet emo, heartbreaking lyrics. Do not fit to any genre of music, and will have you sitting on a rainbow for one song and riding through the fiery depths of hell on a tricycle in the next. A name that can and will never be spelled with the number 21. A fandom in which everyone refers to lead singer Tyler Joseph as a "smol bean" and drummer Josh Dun as a "cinnamon roll".
"You should listen to Twenty One Pilots!"
"Oh, what genre is it?"
"I'm gonna go."

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.
