That chick who always acts as if she is your mother. She will reprimand you at any given time, though usually for acceptable reasons. Nikki's are dream crushers, especially when those dreams involve betta fish and/or rolling chair races. She is also a bad person. A Nikki's soul-mate most definitely is named Scott.
Boy: Let's get a Betta fish!
Girl: NO I AM THE SPAWN OF SATAN AND I SAY NO

Boy: Man youre a nikki
Girl: I love Scott

Boy 1: Let's race rolling chairs
Boy 2: Ok Dude
Girl: NOOOOOOOOO!
Boy 1: Dude she is such a nikki.

A word to describe a whale-like person. One who is fat. One who eats a lot of food. Or a person who steals other people's food as well.
That girl is such a Nikki! See how much she eats?!

A Nikki will claim to love you but will take credit for every good thing you have done. A Nikki will also claim that she is always right and never wrong. A Nikki will also leave you high and dry with her own flesh and blood because she is "stressed" and yet claim to have been loyal, and expect forgiveness when she forgives no one.
"She left you with her kid for how long? Damn, you got Nikki'ied on that one."

The most perfect person youll ever met. Can make you feel loved in an instant, and broken in a day. The one person you go to for help, and no matter what shes feeling she will help. Summary, the most loveable caring person you will ever met. And the sexiest.
That girl, Nikki, Is amazing.
