CALA BOCA GALVAO 

Latest sensation topic on Twitter. Believed by most world to be related to some kind of (inexistent) bird, and even to some new Lady Gaga's song. Its, in fact, the biggest inside joke of all time, by Brazil.

CALA BOCA means SHUT UP. Period.

GALVAO is referred to Galvão Bueno, a sports narrator from Brazil. Really annoying guy. CALA BOCA GALVAO!

Person 1: Hey man, each tweet containing CALA BOCA GALVAO donates some cents to a birds foundation, to save them. I'm doing it a LOT!

Person 2: Are you stupid? Brazil made the whole world look like fools.

Cala boca Galvão

It's a Brazilian Portuguese sentence which means "Shut up, Galvão." It mocks the famous Brazilian TV sports commentor Galvão Bueno, who often overuses catchphrases and tends to talk more than he is supposed to. Organized supporters on stadiums would often yell "Cala boca, Galvão" during a soccer match so that it could be heard by Bueno and the rest of Brazil on TV. Despite all jokes and criticism towards Bueno, he still is one of the most popular and acknowledged sports commentor in Brazil and his famous catchphrases are often used by many Brazilians in many communicative situations.

Some of Galvão Bueno's catchphrases:

- Bem, amigos da Rede Globo... (Very well, friends of Rede Globo...)
- Haja coração! (You must have strong heart!)
- De cara pro vento (Face to face with the wind)
- Ronaldinho!! (Spoken with a long trilled "R")
- Vai que é tua, Tafarel! (Go! It's yours, Tafarel!)

Galvão Bueno: "Haja coração! Na traaaaaaaaaaaaaaaaaaaaveeeeeeeeeeeee!! Na traaaaaaaveeeeee!!"

Brazilian guy watching TV: "Porra, Galvão! Cala essa boca! Cala boca Galvão. CALA BOCA!"

Crowd at the stadium: "CALA BOCA GALVÃO! CALA BOCA GALVÃO!"(repeated many times)

Galvanistic 

galvanism is the concept, uh, the obsolete scientific theory that there is a kind of electricity flowing through our bloodstreams
And that was our life force
I used the term because I came across it in, uh, Mary Shelley's, uh, "Frankenstein"
And that book is sort of an exploration of the theme of creating a character, of making up a person
So I used the term "galvanistic" to allude to that book as a sort of a symbol of how I like, created you as a character
I'm pretending that I know a lot more about you than I actually do
And also to refer to the fact that I've fall—fallen in love with the characters you've created in, uh, your body of work

You galvanistic young boy
You galvanistic young man
You galvanistic young inhuman
You understand
