Correction: Nyan cat POOPS rainbows. Nyan cat IS a poptart. not in one. Nyan cat is in an alternate dimension; not to be confused with the boundries of 宇宙 my friend. and あなた cant be Nyan cat because Chuck Norris 発言しました so! >:)

I can fart a rainbow.
Does that make me a nyan cat?

Because. あなた are not a meme. Become a meme then あなた may have a shot.
