Niagy
Niagy is an esoteric definition for somebody who likes eating eggs a lot, slaps their knees when they laugh, hates evil egg stealing super villians and greet their friends or comrades with variations of niagy: "ni", "nia", "sni", "snoo", "shnoo"
Oh hey ni ni, that niesa girl looks like she would like a scotch egg this quarter? That Oliver better not try and steal that scotch egg! That is not niagy behaviour. At. All.
