A viral video, a meme... It consists of a flying pastry cat and rainbows coming out from "behind".
The song is a random Japanese song... Some people make parodies, such as American Nyan Cat (and play music that fits)...
Tacnayn is the "enemy" of Nyan Cat... The opposite. It's a black waffle cat. The Nyan Cat music is played but only backwards.
It is a viral video and several people have made 3 - 24 hour versions.
NYAN NYAN NYAN!
Jacob listened to Nyan Cat today. He wanted to know why it's cool and why everyone in his school is talking about it.
JACOB: Why is my internet so slow?
SONG STARTS: NYAN NYAN NYAN NYAN NYAN NYAN NYAN NYAN!
The next day... Jacob went to school...
TEACHER: Ummm... Jacob! Why don't you tell the class what you got for number 4?
JACOB: Nyan nyan nyan?
TEACHER: Huh? Please just explain how you got number four and what you got!
TEACHER: This is not a joke! >:(
