Gaijin Rock
Gaijin Rock is when Japanese people scream into microphones about anime and robots while making loud electronic noise that sounds like a toaster having a meltdown.
My cousin tried to sing Gaijin Rock and ended up crying because he forgot the words.
At the concert, the bass was so loud, my teeth started to chatter like a dog in the snow.
My mom said it's just Japanese kids trying to sound cool but failing miserably.
