Usually a girl who is very selfish and self-centered. She cares about no one but herself. She seldom cries because she's a cold-hearted bitch. You might think she's a good friend but she will turn around and stab you in the back quick. Never trust a Nicky. Also, she is very ugly but tries to flaunt herself, but she really just comes off as a slut.. which she is.
To be Nicky is to be selfless, sweet and caring. Honest, real and easy-going. Nicky's are very beautiful inside and out. Envied for their natural kindness and beauty, they love all and are loved by all.
A person who has no idea of their drinking limitations and will often drink to extreme excess. These persons are guilty of becoming coma carpets and creating pavement pizzas. Often seen creating a scene on the dancefloor and falling down stairs or off kerbs.
See that bitch in the gutter, she has obviously done a Nicky.
