Naicy
A Naicy is a weird, clueless person who thinks they're super cool. They get angry when people say Nancy and act like they're the only one in the world who's ever been a Naicy.
Naicy: 'I'm cool.' Me: 'You're not cool. You're a mess.'
Naicy: 'I'm not Nancy.' Me: 'You just said Nancy.'
Naicy: 'I'm unique.' Me: 'You walked into a wall and spilled your drink.'
