Some odd creature pooping out a slightly discolored rainbow while repeatedly screaming nyan to an addictive tune. Can be used as an insult
Yu fucking nyancat!;! Stop screaming mommy

Look at that bird chirping through the air. Hell, it could be Nyancat cat

The creepiest cat ever to come to the internet. A cat with the body of a poptart flying through space with a catchy song featuring the word "nyan".

A cat traveling through space with a poptart as the body, with a rainbow coming out of its ass. Just says nyan over and over. It's cute at first, but gets annoying. Go to to see how long you can stand the nyan-ing for.
Nyan cat is annoying.

1. A cat shoved in a pop tart flying through space shitting rainbows

A disturbingly enthusiastic and adorable Poptart cat that shoots rainbows out of its ass while continually singing a very obnoxious but addicting song. NYAN NYAN NYAN NYAN NYAN NYAN ALL DAY LONG! Has been know to treat certain types of madness and increase hormonal levels in people under the age of 10.
"I was able to watch that Nyan Cat video for 5 Hours, and now have a considerable amount of brain damage!"
