A cat that beams subliminal messages into your brain, slowly devouring it. Once under Nyan Cat's spell, you may only say: Nyan. When saying Nyan, you may notice that your tongue forms a L shape, that is because you are completely under the control of Nyan Cat. You will also find that you begin to eat a lot of pop tarts to make up for the fact that your body is not one. There is no cure for this yet, and if you happen to be tricked into watching Nyan Cat, good luck.
Person #1: Hey man, have you ever heard of Nyan Cat? Somebody wanted me to watch it.
Person #2: Nyan. Nyan nyan nyan nyan nyan.
Person #1: Ok....
Person #2: Nyan. Nyan nyan nyan nyan nyan.
Person #1: Ok....
