Nicotine personified as a woman.

Nicotine is Nikki, Marijuana is Mary Jane, LSD is Lucy, Molly is obviously Molly, Cocaine is almost any White female celebrity (ex: Miley Cyrus, Hannah Montana, Katey Perry, or even just white girl)
Wiz Khalifa: I got a date with Mary Jane. Ya trying' to join?
Logic: No thanks man. I stopped seeing Mary. She just ain't right for me, but Nikki got me pussy whipped

A hot piece of ass who tends to wear glasses and has extremely bouncy playful hair. She gives the best advice and can be looked at as a "sex goddess". She has a strange obbsession with horror movies and fucking certain males even when she has a boyfriend. You will be amazed when you meet a nikki.
"OMG she was totally giving that guy a blowjob even when she has a boyfriend. Gawd she's such a nikki!"
"That girl is my best friend.She's such a nikki."

A loving bubbly person who brings out the best in people, attracts men with her natural beauty and personality and her sexy deep eyes, once you've met her you never want to leave her.

Great in bed (soft and can be wild) and once you have had the experience she leaves you wanting more and more.
A very loyal, respectful person. A lady to be honoured.

First of all, a girl, beautiful to an unforgivable level, both in appearance and in personality. Adventurous, fun, and an example of light in the dark, and hope in despair. Nikki is like the bright stars at night decorating probably one of the most boring things to look at. Second, not only is she a blazing hot chick, she is also a bro, someone who's got your back at all times, and a good partner. Whenever you got trouble, she's somewhere to kick its ass. Third, a girl with no temper, anger is not in her dictionary, because of this the people around her tend to become the same, just can't get pissed off at her or in front of her. Fourth, intelligent and active, your daily source of news and a living encyclopedia. Talented in both sports and career, making some of the most boring things fun when you do it with her. Finally, that girl there who respects and gets respected. A girl who is not reaching perfection, but being reached by perfection. Nikki even when she isn't looking at you, looking at her makes you feel content, makes you smile and brightens your day. So lucky to have her in my life, couldn't ask for better.
Friend:Dude you have like the best girlfriend picked out of the universe.
Me: Are you kidding me? Nikki is the best out of all the best girlfriends out there.
Friend: Man I wish I was you.
Nikki: :) Sorry forever taken, but I got snacks and drinks for us.
Friend: Dammit haha.

The most awesome girl you will ever meet. But she is notorious for stealing mens hearts and being a random psycho person who needs a straight jacket. Anyway, you'd love her!

Friend 2:Yeah?! Well, she stole my boyfriend!
Friend 1:Boo hoo for you
