An
utterance popularized by a man with a rather large
torso,
henceforth referred to as "
Torso." At any time he may start proclaiming NYAAAAAAH!!! in reference to anything, or using it in place of words which sort of sound like it, such as in the case of the city of Nyah'leans.
Nyah, I like titties, I'm a fat
torso, nyaaaah, I made out with
Nick's sister, nyaaaah!!
